1. Interim Financial Statements

(All Registrants)

Capitalized terms and abbreviations appearing in the unaudited combined notes to condensed financial statements are defined in the glossary. Dollars are in millions, except per share data, unless otherwise noted. The specific Registrant to which disclosures are applicable is identified in parenthetical headings in italics above the applicable disclosure or within the applicable disclosure for each Registrant's related activities and disclosures. Within combined disclosures, amounts are disclosed for any Registrant when significant.

The accompanying unaudited condensed financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all of the information and footnote disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation in accordance with GAAP are reflected in the condensed financial statements. All adjustments are of a normal recurring nature, except as otherwise disclosed. Each Registrant's Balance Sheet at December 31, 2019 is derived from that Registrant's 2019 audited Balance Sheet. The financial statements and notes thereto should be read in conjunction with the financial statements and notes contained in each Registrant's 2019 Form 10-K. The results of operations for the three and nine months ended September 30, 2020 are not necessarily indicative of the results to be expected for the full year ending December 31, 2020 or other future periods, because results for interim periods can be disproportionately influenced by various factors, developments and seasonal variations.

2. Summary of Significant Accounting Policies

(All Registrants)

The following accounting policy disclosures represent updates to Note 1 in each Registrant's 2019 Form 10-K and should be read in conjunction with those disclosures.

Current Expected Credit Losses

(All Registrants)

Financing receivable collectability is evaluated using a combination of factors, including past due status based on contractual terms, trends in write-offs and the age of the receivable. Specific events, such as bankruptcies, are also considered when applicable. Adjustments to the reserve for credit losses are made when necessary based on the results of analysis, the aging of receivables and historical and industry trends. The Registrants periodically evaluate the impact of observable external factors on the collectability of the financing receivables to determine if adjustments to the reserve for credit losses should be made based on current conditions or reasonable and supportable forecasts.

Accounts receivable are written off in the period in which the receivable is deemed uncollectible.

(PPL and PPL Electric)

PPL Electric has identified one class of financing receivables, “accounts receivable-customer”, which includes financing receivables for all billed and unbilled sales with residential and non-residential customers. All other financing receivables are classified as other. Within the credit loss model for the residential customer accounts receivables, customers are disaggregated based on their projected propensity to pay, which is derived from historical trends and the current activity of the individual customer accounts. Conversely, the non-residential customer accounts receivables are not further segmented due to the varying nature of the individual customers, which lack readily identifiable risk characteristics for disaggregation.

(PPL, LKE, LG&E and KU)

LKE, LG&E and KU have identified one class of financing receivables, “accounts receivable-customer”, which includes financing receivables for all billed and unbilled sales with customers. All other financing receivables are classified as other.

Asset Impairment (Excluding Investments)

(PPL, LKE, LG&E and KU)

PPL, LKE, LG&E and KU review goodwill for impairment at the reporting unit level annually or more frequently when events or circumstances indicate that the carrying amount of a reporting unit may be greater than the unit's fair value. PPL's, LKE's, LG&E's and KU's reporting units are primarily at the operating segment level.

During the three month period ended March 31, 2020, PPL, LKE, LG&E and KU considered whether the economic events associated with COVID-19, which resulted in PPL’s shares experiencing volatility and a decrease in market value, would more likely than not reduce the fair value of the Registrants’ reporting units below their carrying amounts. See "Risks and Uncertainties" in Note 11 for additional information about COVID-19. Based on our assessment, a quantitative impairment test was not required for the LKE, LG&E and KU reporting units, but was required for the U.K. Regulated segment reporting unit, the allocated goodwill of which was $2.5 billion at March 31, 2020. The test did not indicate impairment of the reporting unit.

During the three month periods ended June 30, 2020 and September 30, 2020, no goodwill impairment triggers were identified. However, an impairment charge could occur in future periods if PPL’s share price or any of the assumptions used in determining fair value of the reporting units are negatively impacted.

(PPL)

On August 10, 2020, PPL announced that it is initiating a formal process to sell its U.K. utility business. As a result of the potential sale, PPL assessed the recoverability of the assets of its U.K. utility business. See Note 9 for additional information.

New Accounting Guidance Adopted

(All Registrants)

Accounting for Financial Instrument Credit Losses

Effective January 1, 2020, the Registrants adopted accounting guidance, using a modified retrospective approach, that requires the use of a current expected credit loss (CECL) model for the measurement of credit losses on financial instruments within the scope of the guidance, which includes accounts receivable. The CECL model requires an entity to measure credit losses using historical information, current information and reasonable and supportable forecasts of future events, rather than the incurred loss impairment model required under previous GAAP. The adoption of this guidance did not have a material impact on the Registrants.

35

Table of Contents

Accounting for Implementation Costs in a Cloud Computing Service Arrangement

Effective January 1, 2020, the Registrants prospectively adopted accounting guidance that requires a customer in a cloud computing hosting arrangement that is a service contract to capitalize implementation costs consistent with internal-use software guidance for non-service arrangements. The guidance requires these capitalized implementation costs to be amortized over the term of the hosting arrangement to the statement of income line item where the service arrangement costs are recorded. The guidance also prescribes the financial statement classification of the capitalized implementation costs and cash flows associated with the arrangement. The adoption of this guidance did not have a material impact on the Registrants.

(PPL, LKE, LG&E and KU)

Simplifying the Test for Goodwill Impairment

Effective January 1, 2020, the Registrants adopted accounting guidance that simplifies the test for goodwill impairment by eliminating the second step of the quantitative test. The second step of the quantitative test required a calculation of the implied fair value of goodwill, which was determined in the same manner as the amount of goodwill in a business combination. Under the new guidance, the fair value of a reporting unit will be compared with the carrying value and an impairment charge will be recognized if the carrying amount exceeds the fair value of the reporting unit. The adoption of this guidance did not have a material impact on the Registrants.

(a)Represents customers of WPD.

(b)Primarily includes revenues from pole attachments, street lighting, other public authorities and other non-core businesses.

(c)Includes wholesale power and transmission revenues. LG&E and KU amounts include intercompany power sales and transmission revenues, which are eliminated upon consolidation at LKE.

(d)In the fourth quarter of 2019, management deemed it appropriate to present the revenue offset associated with network integration transmission service (NITS) as distribution revenue rather than transmission revenue.

As discussed in Note 2 in PPL's 2019 Form 10-K, PPL segments its business by geographic location. Revenues from external customers for each segment/geographic location are reconciled to revenues from contracts with customers in the footnotes to the tables above. PPL Electric's revenues from contracts with customers are further disaggregated by distribution and transmission, which were $407 million and $174 million for the three months ended September 30, 2020 and $1.2 billion and $497 million for the nine months ended September 30, 2020. PPL Electric's revenue from contracts with customers disaggregated by distribution and transmission were $477 million and $112 million for the three months ended September 30, 2019 and $1.4 billion and $318 million for the nine months ended September 30, 2019.

Contract receivables from customers are primarily included in "Accounts receivable - Customer" and "Unbilled revenues" on the Balance Sheets.

The following table shows the accounts receivable and unbilled revenues balances that were impaired for the periods ended September 30.

	Three Months				Nine Months
	2020		2019		2020		2019

The following table shows the balances and certain activity of contract liabilities resulting from contracts with customers.

	PPL		PPL Electric		LKE		LG&E		KU
Contract liabilities at December 31, 2019	$	44	$	21	$	9	$	5	$	4
Contract liabilities at September 30, 2020	40		18		9		5		4
Revenue recognized during the nine months ended September 30, 2020 that was included in the contract liability balance at December 31, 2019	28		9		9		5		4
Contract liabilities at December 31, 2018	$	42	$	23	$	9	$	5	$	4
Contract liabilities at September 30, 2019	42		19		9		5		4
Revenue recognized during the nine months ended September 30, 2019 that was included in the contract liability balance at December 31, 2018	31		11		9		5		4

Contract liabilities result from recording contractual billings in advance for customer attachments to the Registrants' infrastructure and payments received in excess of revenues earned to date. Advanced billings for customer attachments are recognized as revenue ratably over the billing period. Payments received in excess of revenues earned to date are recognized as revenue as services are delivered in subsequent periods.

At September 30, 2020, PPL had $40 million of performance obligations attributable to Corporate and Other that have not been satisfied. Of this amount, PPL expects to recognize approximately $40 million within the next 12 months.

5. Earnings Per Share

(PPL)

Basic EPS is computed by dividing income available to PPL common shareowners by the weighted-average number of common shares outstanding during the applicable period. Diluted EPS is computed by dividing income available to PPL common shareowners by the weighted-average number of common shares outstanding, increased by incremental shares that would be outstanding if potentially dilutive non-participating securities were converted to common shares as calculated using the Treasury Stock Method. Incremental non-participating securities that have a dilutive impact are detailed in the table below. These dilutive securities include the PPL common stock forward sale agreements, which were settled in 2019. The forward sale

agreements were dilutive under the Treasury Stock Method to the extent the average stock price of PPL's common shares exceeded the forward sale price prescribed in the agreements.

(a) The U.K. corporation tax rate was scheduled to be reduced from 19% to 17%, effective April 1, 2020. On March 11, 2020, the U.K. Finance Act 2020 included a cancellation of the tax rate reduction to 17%, thereby maintaining the corporation tax rate at 19%. The Finance Act 2020 was formally enacted on July 22, 2020. The primary impact of the cancellation of the corporation tax rate reduction was an increase in deferred tax liabilities and a corresponding deferred tax expense of $106 million.

(b) During the second quarter of 2019, LKE recorded a deferred income tax benefit associated with two projects placed into service that prepare a generation waste material for reuse and, as a result, qualify for a Kentucky recycling credit. The applicable credit provides tax benefits for a portion of the equipment costs for major recycling projects in Kentucky. A portion of this amount has been reserved due to insufficient Kentucky taxable income projected at LKE.

2020 TCJA Regulatory Update (All Registrants)

In July 2020, the IRS issued final and new proposed regulations relating to limitations on interest deductibility for tax purposes. The Registrants will apply the final regulations beginning in the 2021 tax year. The proposed regulations will apply in the year in which the regulations are issued in final form, which is expected to be in 2021 or later. The Registrants are evaluating the final and proposed regulations, but do not expect the regulations to have a material impact on the Registrants’ financial condition or results of operations.

Kentucky Activities

Rate Case Proceedings

(PPL, LKE, LG&E and KU)

On October 23, 2020, LG&E and KU filed notices of intent with the KPSC to file applications for proposed adjustments of general electric and gas rates on or after November 25, 2020. The applications will also include requests for a CPCN to deploy Advanced Metering Infrastructure and other matters. LG&E and KU cannot predict the outcome of these potential proceedings.

ECR Filings (PPL, LKE, LG&E and KU)

On March 31, 2020, LG&E and KU submitted applications to the KPSC for ECR rate treatment regarding upcoming environmental construction projects relating to the EPA's regulations addressing ELGs. The construction projects are expected to begin in 2021 and continue through 2024 and are estimated to cost approximately $405 million ($153 million at LG&E and $252 million at KU). The applications requested an authorized 9.725% return on equity with respect to these projects consistent with the 2018 Kentucky rate cases approved in April 2019. On September 29, 2020, the KPSC issued orders approving the ECR applications, permitting an authorized return on equity of 9.2% for the applicable projects.

Pennsylvania Activities 

Act 129 (PPL and PPL Electric)

The Pennsylvania Public Utility Code requires electric distribution companies, including PPL Electric, to act as a DSP, which provides electricity generation supply service to customers pursuant to a PUC-approved default service procurement plan. A DSP is able to recover the costs associated with its default service procurement plan.

In March 2020, PPL Electric filed a Petition for Approval of a new default service program and procurement plan with the PUC for the period June 1, 2021 through May 31, 2025. Hearings were held in August 2020. In October 2020, the Administrative Law Judge made a recommended decision which remains pending before the PUC. PPL Electric cannot predict the outcome of this proceeding.

Federal Matters

Challenge to PPL Electric Transmission Formula Rate Return on Equity

(PPL and PPL Electric)

On May 21, 2020, PP&L Industrial Customer Alliance (PPLICA) filed a complaint with the FERC alleging that PPL Electric's base return on equity (ROE) of 11.18% used to determine PPL Electric's formula transmission rate is unjust and unreasonable, and proposing an alternative ROE of 8.0% based on its interpretation of FERC Opinion No. 569. However, also on May 21, 2020, the FERC issued Opinion No. 569-A in response to numerous requests for rehearing of Opinion No. 569, which revised the method for analyzing base ROE. On June 10, 2020, PPLICA filed a Motion to Supplement the May 21, 2020 complaint in which PPLICA continued to allege that PPL Electric’s base ROE is unjust and unreasonable, but revised its analysis of PPL Electric's base ROE to reflect the guidance provided in Opinion No. 569-A. The amended complaint proposed an updated alternative ROE of 8.5% and also requested that the FERC preserve the original refund effective date as established by the filing of the original complaint on May 21, 2020. Several parties have filed motions to intervene, including one party who filed Comments in Support of the original complaint.

On July 10, 2020, PPL Electric filed its Answer and supporting Testimony to the PPLICA filings arguing that the FERC should deny the original and amended complaints as they are without merit and fail to demonstrate the existing base ROE is unjust and unreasonable. In addition, PPL Electric contended any refund effective date should be set for no earlier than June 10, 2020 and PPLICA's proposed replacement ROE should be rejected.

On October 15, 2020, the FERC issued an order on the PPLICA complaints which established hearing and settlement procedures, set a refund effective date of May 21, 2020 and granted the motions to intervene. PPL Electric continues to believe its ROE is just and reasonable and that it has meritorious defenses against the original and amended complaints. At this time, PPL Electric cannot predict the outcome of this matter or the range of possible losses, if any, that may be incurred. However, revenue earned from May 21, 2020 through the settlement of this matter may be subject to refund. A change of 50 basis points to the base ROE would impact PPL Electric's net income by approximately $12 million on an annual basis.

FERC Transmission Rate Filing

(PPL, LKE, LG&E and KU)

In 2018, LG&E and KU applied to the FERC requesting elimination of certain on-going credits to a sub-set of transmission customers relating to the 1998 merger of LG&E's and KU's parent entities and the 2006 withdrawal of LG&E and KU from the Midcontinent Independent System Operator, Inc. (MISO), a regional transmission operator and energy market. The application sought termination of LG&E's and KU's commitment to provide certain Kentucky municipalities mitigation for certain horizontal market power concerns arising out of the 1998 LG&E and KU merger and 2006 MISO withdrawal. The amounts at issue are generally waivers or credits granted to a limited number of Kentucky municipalities for either certain LG&E and KU or MISO transmission charges incurred for transmission service received. Due to the development of robust, accessible energy markets over time, LG&E and KU believe the mitigation commitments are no longer relevant or appropriate. In March 2019, the FERC granted LG&E's and KU's request to remove the ongoing credits, conditioned upon the implementation by LG&E and KU of a transition mechanism for certain existing power supply arrangements, subject to FERC review and approval. In July 2019, LG&E and KU proposed their transition mechanism to the FERC and in September 2019, the FERC rejected the proposed transition mechanism and issued a separate order providing clarifications of certain aspects of the March order. In October 2019, LG&E and KU filed requests for rehearing and clarification on the two September orders. In September 2020, FERC issued its orders in the rehearing process that modified the discussion in, and set aside portions of, the September 2019 orders including adjusting factors impacting the proposed transition mechanism. In October 2020, both LG&E and KU and other parties filed separate motions for rehearing and clarification regarding FERC’s September 2020 orders. A FERC decision on these rehearing requests is expected by November 18, 2020. Certain other petitions for review of the FERC's orders have been filed by multiple parties, including LG&E and KU, with the D.C. Circuit Court of Appeals. LG&E and KU cannot predict the outcome of these proceedings. LG&E and KU currently receive recovery of waivers and credits provided through other rate mechanisms.

(PPL and PPL Electric)

In April 2020, PPL Electric filed its annual transmission formula rate update with the FERC, reflecting a revised revenue requirement that took effect in June 2020.

Purchase of Receivables Program (PPL and PPL Electric)

In accordance with a PUC-approved purchase of accounts receivable program, PPL Electric purchases certain accounts receivable from alternative electricity suppliers at a discount, which reflects a provision for credit losses. The alternative electricity suppliers have no continuing involvement or interest in the purchased accounts receivable. Accounts receivable that are acquired are initially recorded at fair value on the date of acquisition. During the three and nine months ended September 30, 2020, PPL Electric purchased $303 million and $854 million of accounts receivable from alternative suppliers. During the three and nine months ended September 30, 2019, PPL Electric purchased $308 million and $927 million of accounts receivable from alternative suppliers.

Equity Securities

ATM Program

In February 2018, PPL entered into an equity distribution agreement, pursuant to which PPL may sell, from time to time, up to an aggregate of $1.0 billion of its common stock through an at-the-market offering program, including a forward sales component. The compensation paid to the selling agents by PPL may be up to 2% of the gross offering proceeds of the shares. There were no issuances under the ATM program for the nine months ended September 30, 2020.

Distributions

In August 2020, PPL declared a quarterly common stock dividend, payable October 1, 2020, of 41.5 cents per share (equivalent to $1.66 per annum). Future dividends, declared at the discretion of the Board of Directors, will depend upon future earnings, cash flows, financial and legal requirements and other factors.

9. Acquisitions, Development and Divestitures

(PPL)

On August 10, 2020, PPL announced that it has initiated a formal process to sell its U.K. utility business. PPL noted that there can be no assurance of any specific outcome, including whether the sale process will result in the completion of any potential transaction, the timing or terms thereof, the value or benefits that may be realized or the effect that any potential transaction will have on future financial results.

As a result of the potential sale, PPL assessed the recoverability of the assets of its U.K. utility business. PPL prepared a probability-weighted undiscounted cash flow estimate as of September 30, 2020 that considered the likelihood of the possible outcomes of the sale process, including the possibility of not selling the U.K. utility business. The resulting cash flow analysis exceeded the carrying value of the assets of the U.K. utility business. A change in the possible outcomes of the sale process could result in the carrying value of the assets of the U.K. utility business not being recoverable, which could result in an impairment in future periods. The U.K. utility business will continue to be classified as held and used until it meets the criteria to be classified as held for sale, which includes management obtaining a commitment to a plan to sell from its Board of Directors.

Should the U.K. utility business meet the criteria to be classified as held for sale in a future period, PPL will be required at that time to compare the estimated fair value of its investment in the U.K. utility business, less costs to sell, to its carrying value for impairment purposes. The measurement of PPL’s carrying value of the U.K. utility business will include the realization of accumulated other comprehensive losses, which could arise from currency translation adjustments and defined benefit plans associated with the U.K. utility business.

10. Defined Benefits

(PPL, LKE and LG&E)

Certain net periodic defined benefit costs are applied to accounts that are further distributed among capital, expense, regulatory assets and regulatory liabilities, including certain costs allocated to applicable subsidiaries for plans sponsored by PPL Services and LKE. Following are the net periodic defined benefit costs (credits) of the plans sponsored by PPL and its subsidiaries, LKE, and LG&E for the periods ended September 30:

PPL and its subsidiaries are involved in legal proceedings, claims and litigation in the ordinary course of business. PPL and its subsidiaries cannot predict the outcome of such matters, or whether such matters may result in material liabilities, unless otherwise noted.

Talen Litigation (PPL)

Background

In September 2013, one of PPL's former subsidiaries, PPL Montana entered into an agreement to sell its hydroelectric generating facilities. In June 2014, PPL and PPL Energy Supply, the parent company of PPL Montana, entered into various definitive agreements with affiliates of Riverstone to spin off PPL Energy Supply and ultimately combine it with Riverstone's competitive power generation businesses to form a stand-alone company named Talen Energy. In November 2014, after executing the spinoff agreements but prior to the closing of the spinoff transaction, PPL Montana closed the sale of its hydroelectric generating facilities. Subsequently, on June 1, 2015, the spinoff of PPL Energy Supply was completed. Following the spinoff transaction, PPL had no continuing ownership interest in or control of PPL Energy Supply. In connection with the spinoff transaction, PPL Montana became Talen Montana, LLC (Talen Montana), a subsidiary of Talen Energy. Talen Energy Marketing also became a subsidiary of Talen Energy as a result of the June 2015 spinoff of PPL Energy Supply. Talen Energy has owned and operated both Talen Montana and Talen Energy Marketing since the spinoff. At the time of the spinoff, affiliates of Riverstone acquired a 35% ownership interest in Talen Energy. Riverstone subsequently acquired the remaining interests in Talen Energy in a take private transaction in December 2016.

Talen Montana Retirement Plan and Talen Energy Marketing, LLC, Individually and on Behalf of All Others Similarly Situated v. PPL Corporation et al.

On October 29, 2018, Talen Montana Retirement Plan and Talen Energy Marketing filed a putative class action complaint on behalf of current and contingent creditors of Talen Montana who allegedly suffered harm or allegedly will suffer reasonably foreseeable harm as a result of a November 2014 distribution of proceeds from the sale of then-PPL Montana's hydroelectric generating facilities. The action was filed in the Sixteenth Judicial District of the State of Montana, Rosebud County, against PPL and certain of its affiliates and current and former officers and directors (Talen Putative Class Action). Plaintiff asserts claims for, among other things, fraudulent transfer, both actual and constructive; recovery against subsequent transferees; civil conspiracy; aiding and abetting tortious conduct; and unjust enrichment. Plaintiff is seeking avoidance of the purportedly fraudulent transfer, unspecified damages, including punitive damages, the imposition of a constructive trust, and other relief. In December 2018, PPL removed the Talen Putative Class Action from the Sixteenth Judicial District of the State of Montana to the United States District Court for the District of Montana, Billings Division (MT Federal Court). In January 2019, the plaintiff moved to remand the Talen Putative Class Action back to state court, and dismissed without prejudice all current and former PPL Corporation directors from the case. In September 2019, the MT Federal Court granted plaintiff's motion to remand the case back to state court. Although, the PPL defendants petitioned the Ninth Circuit Court of Appeals to grant an appeal of the remand decision, in November 2019, the Ninth Circuit Court of Appeals denied that request and in December 2019, Talen Montana Retirement Plan filed a Second Amended Complaint in the Sixteenth Judicial District of the State of Montana, Rosebud County, which removed Talen Energy Marketing as a plaintiff. In January 2020, PPL defendants filed a motion to dismiss the Second Amended Complaint or, in the alternative, to stay the proceedings pending the resolution of the below mentioned Delaware Action. The Court held a hearing on June 24, 2020 regarding the motion to dismiss. On September 11, 2020, the Court granted PPL defendants' alternative Motion for a Stay of the proceedings.

PPL Corporation et al. vs. Riverstone Holdings LLC, Talen Energy Corporation et al.

On November 30, 2018, PPL, certain PPL affiliates, and certain current and former officers and directors (PPL plaintiffs) filed a complaint in the Court of Chancery of the State of Delaware seeking various forms of relief against Riverstone, Talen Energy and certain of their affiliates (Delaware Action), in response to and as part of the defense strategy for an action filed by Talen Montana, LLC (the Talen Direct Action, since dismissed) and the Talen Putative Class Action described above (together, the Montana Actions) originally filed in Montana state court in October 2018. In the complaint, the PPL plaintiffs ask the Delaware Court of Chancery for declaratory and injunctive relief. This includes a declaratory judgment that, under the separation agreement governing the spinoff of PPL Energy Supply, all related claims that arise must be heard in Delaware; that the statute of limitations in Delaware and the spinoff agreement bar these claims at this time; that PPL is not liable for the claims in either the Talen Direct Action or the Talen Putative Class Action as PPL Montana was solvent at all relevant times; and that the separation agreement requires that Talen Energy indemnify PPL for all losses arising from the debts of Talen Montana, among other things. PPL's complaint also seeks damages against Riverstone for interfering with the separation agreement and against Riverstone affiliates for breach of the implied covenant of good faith and fair dealing. The complaint was subsequently amended on January 11, 2019 and March 20, 2019, to include, among other things, claims related to indemnification with respect to the Montana Actions, request a declaration that the Montana Actions are time-barred under the spinoff agreements, and allege additional facts to support the tortious interference claim. In April 2019, the defendants filed motions to dismiss the amended complaint. In July 2019, the Court heard oral arguments from the parties regarding the motions to dismiss, and in October 2019, the Delaware Court of Chancery issued an opinion sustaining all of the PPL plaintiffs' claims except for the claim for breach of implied covenant of good faith and fair dealing. As a result of the dismissal of the Talen Direct Action in December 2019, in January 2020, Talen Energy filed a new motion to dismiss five of the remaining eight claims in the amended complaint. The Court heard oral argument on the motion to dismiss on May 28, 2020, and on June 22, 2020, issued an opinion denying the motion in its entirety. Discovery is proceeding, and a trial has been scheduled for June 2021.

With respect to each of the Talen-related matters described above, PPL believes that the 2014 distribution of proceeds was made in compliance with all applicable laws and that PPL Montana was solvent at all relevant times. Additionally, the agreements entered into in connection with the spinoff, which PPL and affiliates of Talen Energy and Riverstone negotiated and executed prior to the 2014 distribution, directly address the treatment of the proceeds from the sale of PPL Montana's hydroelectric generating facilities; in those agreements, Talen Energy and Riverstone definitively agreed that PPL was entitled to retain the proceeds.

PPL believes that it has meritorious defenses to the claims made in the Talen Putative Class Action and intends to continue to vigorously defend against this action. The Talen Putative Class Action and the Delaware Action are both in early stages of litigation; at this time, PPL cannot predict the outcome of these matters or estimate the range of possible losses, if any, that PPL might incur as a result of the claims, although they could be material.

(PPL, LKE and LG&E)

Cane Run Environmental Claims

In December 2013, six residents, on behalf of themselves and others similarly situated, filed a class action complaint against LG&E and PPL in the U.S. District Court for the Western District of Kentucky (U.S. District Court) alleging violations of the Clean Air Act, RCRA, and common law claims of nuisance, trespass and negligence. In July 2014, the U.S. District Court

dismissed the RCRA claims and all but one Clean Air Act claim, but declined to dismiss the common law tort claims. In February 2017, the U.S. District Court dismissed PPL as a defendant and dismissed the final federal claim against LG&E, and in April 2017, issued an Order declining to exercise supplemental jurisdiction on the state law claims dismissing the case in its entirety. In June 2017, the plaintiffs filed a class action complaint in Jefferson County, Kentucky Circuit Court, against LG&E alleging state law nuisance, negligence and trespass tort claims. The plaintiffs seek compensatory and punitive damages for alleged property damage due to purported plant emissions on behalf of a class of residents within one to three miles of the plant. On January 8, 2020, the Jefferson Circuit Court issued an order denying the plaintiffs’ request for class certification. On January 14, 2020, the plaintiffs filed a notice of appeal in the Kentucky Court of Appeals with oral arguments scheduled for November 17, 2020. PPL, LKE and LG&E cannot predict the outcome of this matter and an estimate or range of possible losses cannot be determined.

E.W. Brown Environmental Claims

In July 2017, the Kentucky Waterways Alliance and the Sierra Club filed a citizen suit complaint against KU in the U.S. District Court for the Eastern District of Kentucky (U.S. District Court) alleging discharges at the E.W. Brown plant in violation of the Clean Water Act and the plant's water discharge permit, and alleging contamination that may present an imminent and substantial endangerment in violation of the RCRA. The plaintiffs' suit relates to prior notices of intent to file a citizen suit submitted in October and November 2015 and October 2016. These plaintiffs sought injunctive relief ordering KU to take all actions necessary to comply with the Clean Water Act and RCRA, including ceasing the discharges in question, abating effects associated with prior discharges and eliminating the alleged imminent and substantial endangerment. These plaintiffs also sought assessment of civil penalties and an award of litigation costs and attorney fees. In December 2017, the U.S. District Court issued an Order dismissing the Clean Water Act and RCRA complaints against KU in their entirety. In January 2018, the plaintiffs appealed the dismissal Order to the U.S. Court of Appeals for the Sixth Circuit. In September 2018, the U.S. Court of Appeals for the Sixth Circuit issued its ruling affirming the lower court's decision to dismiss the Clean Water Act claims but reversing its dismissal of the RCRA claims against KU and remanding the latter to the U.S. District Court. In October 2018, KU filed a petition for rehearing to the U.S. Court of Appeals for the Sixth Circuit regarding the RCRA claims. In November 2018, the U.S. Court of Appeals for the Sixth Circuit denied KU's petition for rehearing regarding the RCRA claims. In January 2019, KU filed an answer to plaintiffs’ complaint in the U.S. District Court. A trial has been scheduled to begin in February 2021. PPL, LKE and KU cannot predict the outcome of these matters and an estimate or range of possible losses cannot be determined.

KU is undertaking extensive remedial measures at the E.W. Brown plant including work preparing for closure of the former ash pond, implementation of a groundwater remedial action plan and performance of a corrective action plan including aquatic study of adjacent surface waters and risk assessment. The aquatic study and risk assessment are being undertaken pursuant to a 2017 agreed Order with the Kentucky Energy and Environment Cabinet (KEEC). KU conducted sampling of Herrington Lake in 2017 and 2018. In June 2019, KU submitted to the KEEC the required aquatic study and risk assessment, conducted by an independent third-party consultant, finding that discharges from the E.W. Brown plant have not had any significant impact on Herrington Lake and that the water in the lake is safe for recreational use and meets safe drinking water standards. However, until the KEEC assesses the study and issues any regulatory determinations, PPL, LKE and KU are unable to determine whether additional remedial measures will be required at the E.W. Brown plant.

Air

Sulfuric Acid Mist Emissions (PPL, LKE and LG&E)

In June 2016, the EPA issued a notice of violation under the Clean Air Act alleging that LG&E violated applicable rules relating to sulfuric acid mist emissions at its Mill Creek plant. The notice alleges failure to install proper controls, failure to operate the facility consistent with good air pollution control practice, and causing emissions exceeding applicable requirements or constituting a nuisance or endangerment. LG&E believes it has complied with applicable regulations during the relevant time period. On July 31, 2020, the U.S. Department of Justice filed a complaint in the U.S. District Court for the Western District of Kentucky alleging violations specified in the EPA notice of violation and seeking civil penalties and injunctive relief. In October 2020, LG&E filed a motion to dismiss the complaint. In October 2020, the U.S. Department of Justice indicated plans to file an amended complaint, as authorized by an agreed order of the court and parties. PPL, LKE and LG&E are unable to predict the outcome of this matter or the potential impact on operations of the Mill Creek plant, including increased capital or operating costs, and potential civil penalties or remedial measures, if any. An estimate or range of possible losses cannot be determined.

Water/Waste

(PPL, LKE, LG&E and KU)

ELGs

In 2015, the EPA finalized ELGs for wastewater discharge permits for new and existing steam electricity generating facilities. These guidelines require deployment of additional control technologies providing physical, chemical and biological treatment and mandate operational changes including "no discharge" requirements for certain wastewaters. The implementation date for individual generating stations was to be determined by the states on a case-by-case basis according to criteria provided by the

55

Table of Contents

EPA. Legal challenges to the final rule were consolidated before the U.S. Court of Appeals for the Fifth Circuit. In April 2017, the EPA announced that it would grant petitions for reconsideration of the rule. In September 2017, the EPA issued a rule to postpone the compliance date for certain requirements. On October 13, 2020, the EPA published final revisions to its best available technology standards for certain wastewaters and potential extensions to compliance dates. The rule will be implemented by the states or applicable permitting authorities in the course of their normal permitting activities. LG&E and KU have developed responsive compliance strategies and schedules. Certain aspects of these compliance plans and estimates relate to developments in state water quality standards, which are separate from the ELG rule or its implementation. Certain costs are included in the Registrants' capital plans and expected to be recovered from customers through rate recovery mechanisms, but additional costs and recovery will depend on further regulatory developments at the state level. See Note 7 for additional information regarding LG&E’s and KU’s applications for ECR rate treatment of construction costs relating to regulations addressing ELGs.

CCRs

In 2015, the EPA issued a final rule governing management of CCRs which include fly ash, bottom ash and sulfur dioxide scrubber wastes. The CCR Rule imposes extensive new requirements for certain CCR impoundments and landfills, including public notifications, location restrictions, design and operating standards, groundwater monitoring and corrective action requirements, and closure and post-closure care requirements, and specifies restrictions relating to the beneficial use of CCRs. In July 2018, the EPA issued a final rule extending the deadline for closure of certain impoundments and adopting other substantive changes. In August 2018, the D.C. Circuit Court of Appeals vacated and remanded portions of the CCR Rule. In December 2019, the EPA addressed the deficiencies identified by the court and proposed amendments to change the closure deadline. In August 2020, the EPA published a final rule extending the deadline to initiate closure to April 11, 2021, while providing for certain extensions. EPA has announced that additional amendments to the rule are planned. PPL, LKE, LG&E and KU are unable to predict the outcome of the ongoing litigation and rulemaking or potential impacts on current LG&E and KU compliance plans. The Registrants are currently finalizing closure plans and schedules.

In January 2017, Kentucky issued a new state rule relating to CCR management, effective May 2017, aimed at reflecting the requirements of the federal CCR rule. As a result of a subsequent legal challenge, in January 2018, the Franklin County, Kentucky Circuit Court issued an opinion invalidating certain procedural elements of the rule. LG&E and KU presently operate their facilities under continuing permits authorized under the former program and do not currently anticipate material impacts as a result of the judicial ruling. The Kentucky Energy and Environmental Cabinet has announced it intends to propose new state rules aimed at addressing procedural deficiencies identified by the court and providing the regulatory framework necessary for operation of the state program in lieu of the federal CCR Rule. Associated costs are expected to be subject to rate recovery.

LG&E and KU received KPSC approval for a compliance plan providing for the closure of impoundments at the Mill Creek, Trimble County, E.W. Brown, and Ghent stations, and construction of process water management facilities at those plants. In addition to the foregoing measures required for compliance with the federal CCR rule, KU also received KPSC approval for its plans to close impoundments at the retired Green River, Pineville and Tyrone plants to comply with applicable state law. Since 2017, LG&E and KU have commenced closure of many of the subject impoundments and have completed closure of some of their smaller impoundments. LG&E and KU expect to commence closure of the remaining impoundments no later than April 2021. LG&E and KU generally expect to complete impoundment closures within five years of commencement, although a longer period may be required to complete closure of some facilities. Associated costs are expected to be subject to rate recovery.

In connection with the final CCR rule, LG&E and KU recorded adjustments to existing AROs beginning in 2015 and continue to record adjustments as required. See Note 16 for additional information. Further changes to AROs, current capital plans or operating costs may be required as estimates are refined based on closure developments, groundwater monitoring results, and regulatory or legal proceedings. Costs relating to this rule are subject to rate recovery.

Superfund and Other Remediation

PPL Electric, LG&E and KU are potentially responsible for investigating and remediating contamination under the federal Superfund program and similar state programs. Actions are under way at certain sites including former coal gas manufacturing plants in Pennsylvania and Kentucky previously owned or operated by, or currently owned by predecessors or affiliates of, PPL Electric, LG&E and KU. PPL Electric is potentially responsible for a share of clean-up costs at certain sites including the

56

Table of Contents

Columbia Gas Plant site and the Brodhead site. Clean-up actions have been or are being undertaken at all of these sites, the costs of which have not been and are not expected to be significant to PPL Electric.

As of September 30, 2020 and December 31, 2019, PPL Electric had a recorded liability of $10 million representing its best estimate of the probable loss to be incurred to remediate the sites identified above. Depending on the outcome of investigations at identified sites where investigations have not begun or been completed, or developments at sites for which information is incomplete, additional costs of remediation could be incurred. PPL Electric, LG&E and KU lack sufficient information about such additional sites to estimate any potential liability or range of reasonably possible losses, if any, related to these sites. Such costs, however, are not currently expected to be significant.

The EPA is evaluating the risks associated with polycyclic aromatic hydrocarbons and naphthalene, chemical by-products of coal gas manufacturing. As a result, individual states may establish stricter standards for water quality and soil cleanup, that could require several PPL subsidiaries to take more extensive assessment and remedial actions at former coal gas manufacturing plants. PPL, PPL Electric, LKE, LG&E and KU cannot estimate a range of possible losses, if any, related to these matters.

Regulatory Issues (All Registrants)

See Note 7 for information on regulatory matters related to utility rate regulation.

Electricity - Reliability Standards

The NERC is responsible for establishing and enforcing mandatory reliability standards (Reliability Standards) regarding the bulk electric system in North America. The FERC oversees this process and independently enforces the Reliability Standards.

The Reliability Standards have the force and effect of law and apply to certain users of the bulk electric system, including electric utility companies, generators and marketers. Under the Federal Power Act, the FERC may assess civil penalties for certain violations.

PPL Electric, LG&E and KU monitor their compliance with the Reliability Standards and self-report or self-log potential violations of applicable reliability requirements whenever identified, and submit accompanying mitigation plans, as required. The resolution of a small number of potential violations is pending. Penalties incurred to date have not been significant. Any Regional Reliability Entity determination concerning the resolution of violations of the Reliability Standards remains subject to the approval of the NERC and the FERC.

In the course of implementing their programs to ensure compliance with the Reliability Standards by those PPL affiliates subject to the standards, certain other instances of potential non-compliance may be identified from time to time. The Registrants cannot predict the outcome of these matters, and an estimate or range of possible losses cannot be determined.

Other

Labor Union Agreements

(LKE and KU)

In August 2020, KU and the United Steelworkers of America ratified a three-year labor agreement through August 2023. The agreement covers approximately 48 employees. The terms of the new labor agreement are not expected to have a significant impact on the financial results of LKE or KU.

(LKE and LG&E)

On November 4, 2020, LG&E and the IBEW reached an agreement in principle regarding a new three-year collective bargaining agreement. The proposed agreement is to be submitted to a vote of IBEW union members during early November 2020. The agreement covers approximately 640 employees. The terms of the proposed labor agreement are not expected to have a significant impact on the financial results of LKE or LG&E. The Registrants cannot predict the ultimate outcome of this matter.

Guarantees and Other Assurances

(All Registrants)

In the normal course of business, the Registrants enter into agreements that provide financial performance assurance to third parties on behalf of certain subsidiaries. Such agreements include, for example, guarantees, stand-by letters of credit issued by financial institutions and surety bonds issued by insurance companies. These agreements are entered into primarily to support or enhance the creditworthiness attributed to a subsidiary on a stand-alone basis or to facilitate the commercial activities in which these subsidiaries engage.

(PPL)

PPL fully and unconditionally guarantees all of the debt securities of PPL Capital Funding.

(All Registrants)

The table below details guarantees provided as of September 30, 2020. "Exposure" represents the estimated maximum potential amount of future payments that could be required to be made under the guarantee. The probability of expected payment/performance under each of these guarantees is remote except for "WPD guarantee of pension and other obligations of unconsolidated entities," for which PPL has a total recorded liability of $5 million at September 30, 2020 and December 31, 2019. For reporting purposes, on a consolidated basis, all guarantees of PPL Electric, LKE, LG&E and KU also apply to PPL, and all guarantees of LG&E and KU also apply to LKE.

	Exposure at September 30, 2020			Expiration Date
PPL
WPD indemnifications for entities in liquidation and sales of assets	$	10	(a)	2022
WPD guarantee of pension and other obligations of unconsolidated entities	90		(b)
LKE
Indemnification of lease termination and other divestitures	200		(c)	2021
LG&E and KU
LG&E and KU obligation of shortfall related to OVEC			(d)

(a)Indemnification to the liquidators and certain others for existing liabilities or expenses or liabilities arising during the liquidation process. The indemnifications are limited to distributions made from the subsidiary to its parent either prior or subsequent to liquidation or are not explicitly stated in the agreements. The indemnifications generally expire two to seven years subsequent to the date of dissolution of the entities. The exposure noted only includes those cases where the agreements provide for specific limits.

In connection with their sales of various businesses, WPD and its affiliates have provided the purchasers with indemnifications that are standard for such transactions, including indemnifications for certain pre-existing liabilities and environmental and tax matters or have agreed to continue their obligations under existing third-party guarantees, either for a set period of time following the transactions or upon the condition that the purchasers make reasonable efforts to terminate the guarantees. Additionally, WPD and its affiliates remain secondarily responsible for lease payments under certain leases that they have assigned to third parties.

(b)Relates to certain obligations of discontinued or modified electric associations that were guaranteed at the time of privatization by the participating members. Costs are allocated to the members and can be reallocated if an existing member becomes insolvent. At September 30, 2020, WPD has recorded an estimated discounted liability for which the expected payment/performance is probable. Neither the expiration date nor the maximum amount of potential payments for certain obligations is explicitly stated in the related agreements, and as a result, the exposure has been estimated.

(c)LKE provides certain indemnifications covering the due and punctual payment, performance and discharge by each party of its respective obligations. The most comprehensive of these guarantees is the LKE guarantee covering operational, regulatory and environmental commitments and indemnifications made by WKE under a 2009 Transaction Termination Agreement. This guarantee has a term of 12 years ending July 2021, and a maximum exposure of $200 million exclusive of certain items such as government fines and penalties that may exceed the maximum. Additionally, LKE has indemnified various third parties related to historical obligations for other divested subsidiaries and affiliates. The indemnifications vary by entity and the maximum exposures range from being capped at the sale price to no specified maximum. LKE could be required to perform on these indemnifications in the event of covered losses or liabilities being claimed by an indemnified party. LKE cannot predict the ultimate outcomes of the various indemnification scenarios, but does not expect such outcomes to result in significant losses above the amounts recorded.

(d)Pursuant to the OVEC power purchase contract, LG&E and KU are obligated to pay for their share of OVEC's excess debt service, post-retirement and decommissioning costs, as well as any shortfall from amounts included within a demand charge designed and expected to cover these costs over the term of the contract. LKE's proportionate share of OVEC's outstanding debt was $105 million at September 30, 2020, consisting of LG&E's share of $73 million and KU's share of $32 million. The maximum exposure and the expiration date of these potential obligations are not presently determinable. See "Energy Purchase Commitments" in Note 13 in PPL's, LKE's, LG&E's and KU's 2019 Form 10-K for additional information on the OVEC power purchase contract.

In March 2018, a sponsor with a 4.85% pro-rata share of OVEC obligations filed for bankruptcy under Chapter 11 and, in August 2018, received a rejection order for the OVEC power purchase contract in the bankruptcy proceeding. OVEC and other entities challenged the contract rejection, the

bankruptcy plan confirmation and regulatory aspects of the plan in various forums. In May 2020, OVEC and the relevant sponsor announced a settlement resolving all disputed matters in the bankruptcy and other proceedings, including providing that the sponsor will withdraw its request to reject the power purchase agreement. The settlement was implemented in July 2020. Periodically, OVEC and certain of its sponsors, including LG&E and KU, may consider certain potential additional credit support actions to preserve OVEC's access to credit markets, including establishing or continuing debt reserve accounts or other changes involving OVEC's existing short and long-term debt.

The Registrants provide other miscellaneous guarantees through contracts entered into in the normal course of business. These guarantees are primarily in the form of indemnification or warranties related to services or equipment and vary in duration. The amounts of these guarantees often are not explicitly stated, and the overall maximum amount of the obligation under such guarantees cannot be reasonably estimated. Historically, no significant payments have been made with respect to these types of guarantees and the probability of payment/performance under these guarantees is remote.

PPL, on behalf of itself and certain of its subsidiaries, maintains insurance that covers liability assumed under contract for bodily injury and property damage. The coverage provides maximum aggregate coverage of $225 million. This insurance may be applicable to obligations under certain of these contractual arrangements.

Risks and Uncertainties (All Registrants)

The COVID-19 pandemic has disrupted the U.S. and global economies and continues to present extraordinary challenges to businesses, communities, workforces and markets. In the U.S. and throughout the world, governmental authorities have taken urgent and extensive actions to contain the spread of the virus and mitigate known or foreseeable impacts. In the Registrants’ service territories, mitigation measures have included quarantines, stay-at-home orders, travel restrictions, reduced operations or closures of businesses, schools and governmental agencies, and legislative or regulatory actions to address health or other pandemic-related concerns, all of which have the potential to adversely impact the Registrants' business and operations, especially if these measures remain in effect for a prolonged period of time.

To date, the Registrants have not experienced a significant impact on their business, results of operations, financial condition, liquidity, operations or on their supply chain as a result of COVID-19; however, the duration and severity of the outbreak and its ultimate effects on the global economy, the financial markets, or the Registrants’ workforce, customers and suppliers are uncertain. A protracted slowdown of broad sectors of the economy, prolonged or pervasive restrictions on businesses and their workforces, or significant changes in legislation or regulatory policy to address the COVID-19 pandemic all present significant risks to the Registrants. These or other unpredictable events resulting from the pandemic could further reduce customer demand for electricity and gas, impact the Registrants’ employees and supply chains, result in an increase in certain costs, delay payments or increase bad debts, or result in changes in the fair value of their assets and liabilities, which could materially and adversely affect the Registrants’ business, results of operations, financial condition or liquidity.

Support Costs (PPL Electric, LKE, LG&E and KU)

PPL Services, PPL EU Services and LKS provide PPL, PPL Electric, LKE, their respective subsidiaries, including LG&E and KU, and each other with administrative, management and support services. For all services companies, the costs of directly assignable and attributable services are charged to the respective recipients as direct support costs. General costs that cannot be directly assigned or attributed to a specific entity are allocated and charged to the respective recipients as indirect support costs. PPL Services and PPL EU Services use a three-factor methodology that includes the applicable recipients' invested capital, operation and maintenance expenses and number of employees to allocate indirect costs. PPL Services may also use a ratio of overall direct and indirect costs or a weighted average cost ratio. LKS bases its indirect allocations on the subsidiaries' number of employees, total assets, revenues, number of customers and/or other statistical information. PPL Services, PPL EU Services and LKS charged the following amounts for the periods ended September 30, including amounts applied to accounts that are further distributed between capital and expense on the books of the recipients, based on methods that are believed to be reasonable.

VEBA Funds Receivable (PPL Electric)

In May 2018, PPL received a favorable private letter ruling from the IRS permitting a transfer of excess funds from the PPL Bargaining Unit Retiree Health Plan VEBA to a new subaccount within the VEBA, to be used to pay medical claims of active bargaining unit employees. Based on PPL Electric's participation in PPL’s Other Postretirement Benefit plan, PPL Electric was allocated a portion of the excess funds from PPL Services. These funds have been recorded as an intercompany receivable on PPL Electric's Balance Sheets. The receivable balance decreases as PPL Electric pays incurred medical claims and is reimbursed by PPL Services. The intercompany receivable balance associated with these funds was $27 million as of September 30, 2020, of which $10 million was reflected in "Accounts receivable from affiliates" and $17 million was reflected in "Other noncurrent assets" on the PPL Electric Balance Sheet. The intercompany receivable balance associated with these funds was $32 million as of December 31, 2019, of which $10 million was reflected in "Accounts receivable from affiliates" and $22 million was reflected in "Other noncurrent assets" on the PPL Electric Balance Sheet.

14. Fair Value Measurements

(All Registrants)

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). A market approach (generally, data from market transactions), an income approach (generally, present value techniques and option-pricing models) and/or a cost approach (generally, replacement cost) are used to measure the fair value of an asset or liability, as appropriate. These valuation approaches incorporate inputs such as observable, independent market data and/or unobservable data that management believes are predicated on the assumptions market participants would use to price an asset or liability. These inputs may incorporate, as applicable, certain risks such as nonperformance risk, which includes credit risk. The fair value of a group of financial assets and liabilities is measured on a net basis. See Note 1 in each Registrant's 2019 Form 10-K for information on the levels in the fair value hierarchy.

Recurring Fair Value Measurements

The assets and liabilities measured at fair value were:

Special Use Funds

(PPL)

The special use funds are investments restricted for paying active union employee medical costs. In May 2018, PPL received a favorable private letter ruling from the IRS permitting a transfer of excess funds from the PPL Bargaining Unit Retiree Health Plan VEBA to a new subaccount within the VEBA to be used to pay medical claims of active bargaining unit employees. The funds are invested primarily in commingled debt and equity funds measured at NAV and are classified as investments in equity securities. Changes in fair value of the funds are recorded to the Statements of Income.

Price Risk Management Assets/Liabilities - Interest Rate Swaps/Foreign Currency Contracts/Cross-Currency Swaps

(PPL, LKE, LG&E and KU)

To manage interest rate risk, PPL, LKE, LG&E and KU use interest rate contracts such as forward-starting swaps, floating-to-fixed swaps and fixed-to-floating swaps. To manage foreign currency exchange risk, PPL uses foreign currency contracts such as forwards, options and cross-currency swaps that contain characteristics of both interest rate and foreign currency contracts. An income approach is used to measure the fair value of these contracts, utilizing readily observable inputs, such as forward interest rates (e.g., LIBOR and government security rates) and forward foreign currency exchange rates (e.g., GBP), as well as inputs that may not be observable, such as credit valuation adjustments. In certain cases, market information cannot practicably be obtained to value credit risk and therefore internal models are relied upon. These models use projected probabilities of default and estimated recovery rates based on historical observances. When the credit valuation adjustment is significant to the overall valuation, the contracts are classified as Level 3.

15. Derivative Instruments and Hedging Activities

Risk Management Objectives

(All Registrants)

PPL has a risk management policy approved by the Board of Directors to manage market risk associated with commodities, interest rates on debt issuances and foreign exchange (including price, liquidity and volumetric risk) and credit risk (including non-performance risk and payment default risk). The Risk Management Committee, comprised of senior management and chaired by the Senior Director-Risk Management, oversees the risk management function. Key risk control activities designed to ensure compliance with the risk policy and detailed programs include, but are not limited to, credit review and approval, validation of transactions, verification of risk and transaction limits, value-at-risk analyses (VaR, a statistical model that attempts to estimate the value of potential loss over a given holding period under normal market conditions at a given confidence level) and the coordination and reporting of the Enterprise Risk Management program.

Market Risk

Market risk includes the potential loss that may be incurred as a result of price changes associated with a particular financial or commodity instrument as well as market liquidity and volumetric risks. Forward contracts, futures contracts, options, swaps and structured transactions are utilized as part of risk management strategies to minimize unanticipated fluctuations in earnings caused by changes in commodity prices, interest rates and foreign currency exchange rates. Many of these contracts meet the definition of a derivative. All derivatives are recognized on the Balance Sheets at their fair value, unless NPNS is elected.

The following summarizes the market risks that affect PPL and its subsidiaries.

Interest Rate Risk

•PPL and its subsidiaries are exposed to interest rate risk associated with forecasted fixed-rate and existing floating-rate debt issuances. PPL and WPD hold over-the-counter cross currency swaps to limit exposure to market fluctuations on interest and principal payments from changes in foreign currency exchange rates and interest rates. PPL, LKE and LG&E utilize over-the-counter interest rate swaps to limit exposure to market fluctuations on floating-rate debt. PPL, WPD, LKE, LG&E and KU utilize forward starting interest rate swaps to hedge changes in benchmark interest rates, when appropriate, in connection with future debt issuances.

•PPL and its subsidiaries are exposed to interest rate risk associated with debt securities and derivatives held by defined benefit plans. This risk is significantly mitigated to the extent that the plans are sponsored at, or sponsored on behalf of, the regulated domestic utilities and for certain plans at WPD due to the recovery methods in place.

64

Table of Contents

Foreign Currency Risk (PPL)

•PPL is exposed to foreign currency exchange risk primarily associated with its investments in and earnings of U.K. affiliates.

(All Registrants)

Commodity Price Risk

PPL is exposed to commodity price risk through its domestic subsidiaries as described below.

•PPL Electric is required to purchase electricity to fulfill its obligation as a PLR. Potential commodity price risk is insignificant and mitigated through its PUC-approved cost recovery mechanism and full-requirement supply agreements to serve its PLR customers which transfer the risk to energy suppliers.

•LG&E's and KU's rates include certain mechanisms for fuel, fuel-related expenses and energy purchases. In addition, LG&E's rates include a mechanism for natural gas supply expenses. These mechanisms generally provide for timely recovery of market price fluctuations associated with these expenses.

Volumetric Risk

Volumetric risk is the risk related to the changes in volume of retail sales due to weather, economic conditions or other factors. PPL is exposed to volumetric risk through its subsidiaries as described below.

•WPD is exposed to volumetric risk which is significantly mitigated as a result of the method of regulation in the U.K. Under the RIIO-ED1 price control regulations, recovery of such exposure occurs on a two year lag. See Note 1 in PPL's 2019 Form 10-K for additional information on revenue recognition under RIIO-ED1.

•PPL Electric, LG&E and KU are exposed to volumetric risk on retail sales, mainly due to weather and other economic conditions for which there is limited mitigation between rate cases.

Equity Securities Price Risk

•PPL and its subsidiaries are exposed to equity securities price risk associated with the fair value of the defined benefit plans' assets. This risk is significantly mitigated at the regulated domestic utilities and for certain plans at WPD due to the recovery methods in place.

•PPL is exposed to equity securities price risk from future stock sales and/or purchases.

Credit Risk

Credit risk is the potential loss that may be incurred due to a counterparty's non-performance.

PPL is exposed to credit risk from "in-the-money" interest rate and foreign currency derivatives with financial institutions, as well as additional credit risk through certain of its subsidiaries, as discussed below.

In the event a supplier of PPL Electric, LG&E or KU defaults on its obligation, those Registrants would be required to seek replacement power or replacement fuel in the market. In general, subject to regulatory review or other processes, appropriate incremental costs incurred by these entities would be recoverable from customers through applicable rate mechanisms, thereby mitigating the financial risk for these entities.

PPL and its subsidiaries have credit policies in place to manage credit risk, including the use of an established credit approval process, daily monitoring of counterparty positions and the use of master netting agreements or provisions. These agreements generally include credit mitigation provisions, such as margin, prepayment or collateral requirements. PPL and its subsidiaries may request additional credit assurance, in certain circumstances, in the event that the counterparties' credit ratings fall below investment grade, their tangible net worth falls below specified percentages or their exposures exceed an established credit limit.

Master Netting Arrangements (PPL, LKE, LG&E and KU)

Net derivative positions on the balance sheets are not offset against the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) under master netting arrangements.

PPL had a $9 million and $14 million obligation to return cash collateral under master netting arrangements at September 30, 2020 and December 31, 2019.

LKE, LG&E and KU had no obligation to return cash collateral under master netting arrangements at September 30, 2020 and December 31, 2019.

PPL, LKE and LG&E posted $1 million of cash collateral under master netting arrangements at September 30, 2020. KU had no obligation to post cash collateral under master netting arrangements at September 30, 2020. PPL, LKE, LG&E and KU had no obligation to post cash collateral under master netting arrangements at December 31, 2019.

See "Offsetting Derivative Instruments" below for a summary of derivative positions presented in the balance sheets where a right of setoff exists under these arrangements.

Interest Rate Risk

(All Registrants)

PPL and its subsidiaries issue debt to finance their operations, which exposes them to interest rate risk. A variety of financial derivative instruments are utilized to adjust the mix of fixed and floating interest rates in their debt portfolios, adjust the duration of the debt portfolios and lock in benchmark interest rates in anticipation of future financing, when appropriate. Risk limits under PPL's risk management program are designed to balance risk exposure to volatility in interest expense and changes in the fair value of the debt portfolio due to changes in benchmark interest rates. In addition, the interest rate risk of certain subsidiaries is potentially mitigated as a result of the existing regulatory framework or the timing of rate cases.

Cash Flow Hedges (PPL)

Interest rate risks include exposure to adverse interest rate movements for outstanding variable rate debt and for future anticipated financings. Financial interest rate swap contracts that qualify as cash flow hedges may be entered into to hedge floating interest rate risk associated with both existing and anticipated debt issuances. At September 30, 2020, PPL held an aggregate notional value in interest rate swap contracts of £126 million (approximately $168 million based on spot rates) that mature in 2035 to hedge interest payments on WPD's £250 million debt issuance which occurred in October 2020.

At September 30, 2020, PPL held an aggregate notional value in cross-currency interest rate swap contracts of $702 million that range in maturity from 2021 through 2028 to hedge the interest payments and principal of WPD's U.S. dollar-denominated senior notes.

Cash flow hedges are discontinued if it is no longer probable that the original forecasted transaction will occur by the end of the originally specified time period and any amounts previously recorded in AOCI are reclassified into earnings once it is determined that the hedged transaction is not probable of occurring.

For the three and nine months ended September 30, 2020 and 2019, PPL had no cash flow hedges reclassified into earnings associated with discontinued cash flow hedges.

At September 30, 2020, the amount of accumulated net unrecognized after-tax gains (losses) on qualifying derivatives expected to be reclassified into earnings during the next 12 months is insignificant. Amounts are reclassified as the hedged interest expense is recorded.

Economic Activity (PPL, LKE and LG&E)

LG&E enters into interest rate swap contracts that economically hedge interest payments. Because realized gains and losses from the swaps, including terminated swap contracts, are recoverable through regulated rates, any subsequent changes in fair value of these derivatives are included in regulatory assets or liabilities until they are realized as interest expense. Realized gains and losses are recognized in "Interest Expense" on the Statements of Income at the time the underlying hedged interest

expense is recorded. At September 30, 2020, LG&E held contracts with a notional amount of $147 million that range in maturity through 2033.

Foreign Currency Risk (PPL)

PPL is exposed to foreign currency risk, primarily through investments in and earnings of U.K. affiliates. PPL has adopted a foreign currency risk management program designed to hedge certain foreign currency exposures, including firm commitments, recognized assets or liabilities, anticipated transactions, including the previously announced potential sale of its U.K. utility business, and net investments. In addition, PPL enters into financial instruments to protect against foreign currency translation risk of expected GBP earnings.

Net Investment Hedges

PPL enters into foreign currency contracts on behalf of a subsidiary to protect the value of a portion of its net investment in WPD. There were no contracts outstanding at September 30, 2020.

At September 30, 2020 and December 31, 2019, PPL had $33 million and $32 million of accumulated net investment hedge after tax gains (losses) that were included in the foreign currency translation adjustment component of AOCI.

Economic Activity

PPL enters into foreign currency contracts on behalf of a subsidiary to economically hedge GBP-denominated anticipated earnings. At September 30, 2020, the total exposure hedged by PPL was approximately £340 million (approximately $482 million based on contracted rates). These contracts have termination dates ranging from October 2020 through July 2021.

Accounting and Reporting

(All Registrants)

All derivative instruments are recorded at fair value on the Balance Sheet as an asset or liability unless NPNS is elected. NPNS contracts include certain full requirement purchase contracts and other physical purchase contracts. Changes in the fair value of derivatives not designated as NPNS are recognized in earnings unless specific hedge accounting criteria are met and designated as such, except for the changes in fair values of LG&E's interest rate swaps that are recognized as regulatory assets or regulatory liabilities. See Note 7 for amounts recorded in regulatory assets and regulatory liabilities at September 30, 2020 and December 31, 2019.

See Note 1 in each Registrant's 2019 Form 10-K for additional information on accounting policies related to derivative instruments.

Offsetting Derivative Instruments

PPL, LKE, LG&E and KU or certain of their subsidiaries have master netting arrangements in place and also enter into agreements pursuant to which they purchase or sell certain energy and other products. Under the agreements, upon termination of the agreement as a result of a default or other termination event, the non-defaulting party typically would have a right to set off amounts owed under the agreement against any other obligations arising between the two parties (whether under the agreement or not), whether matured or contingent and irrespective of the currency, place of payment or place of booking of the obligation.

PPL, LKE, LG&E and KU have elected not to offset derivative assets and liabilities and not to offset net derivative positions against the right to reclaim cash collateral pledged (an asset) or the obligation to return cash collateral received (a liability) under derivatives agreements. The table below summarizes the derivative positions presented in the balance sheets where a right of setoff exists under these arrangements and related cash collateral received or pledged.

Credit Risk-Related Contingent Features

Certain derivative contracts contain credit risk-related contingent features which, when in a net liability position, would permit the counterparties to require the transfer of additional collateral upon a decrease in the credit ratings of PPL, LKE, LG&E and KU or certain of their subsidiaries. Most of these features would require the transfer of additional collateral or permit the counterparty to terminate the contract if the applicable credit rating were to fall below investment grade. Some of these features also would allow the counterparty to require additional collateral upon each downgrade in credit rating at levels that remain above investment grade. In either case, if the applicable credit rating were to fall below investment grade, and assuming no assignment to an investment grade affiliate were allowed, most of these credit contingent features require either immediate payment of the net liability as a termination payment or immediate and ongoing full collateralization on derivative instruments in net liability positions.

Additionally, certain derivative contracts contain credit risk-related contingent features that require adequate assurance of performance be provided if the other party has reasonable concerns regarding the performance of PPL's, LKE's, LG&E's and KU's obligations under the contracts. A counterparty demanding adequate assurance could require a transfer of additional collateral or other security, including letters of credit, cash and guarantees from a creditworthy entity. This would typically involve negotiations among the parties. However, amounts disclosed below represent assumed immediate payment or immediate and ongoing full collateralization for derivative instruments in net liability positions with "adequate assurance" features.

(PPL, LKE and LG&E)

At September 30, 2020, derivative contracts in a net liability position that contain credit risk-related contingent features, collateral posted on those positions and the related effect of a decrease in credit ratings below investment grade are summarized as follows:

16. Asset Retirement Obligations

(PPL, LKE, LG&E and KU)

PPL's, LKE's, LG&E's and KU's ARO liabilities are primarily related to CCR closure costs. See Note 11 for information on the CCR rule. LG&E also has AROs related to natural gas mains and wells. LG&E's and KU's transmission and distribution lines largely operate under perpetual property easement agreements, which do not generally require restoration upon removal of the property. Therefore, no material AROs are recorded for transmission and distribution assets. For LKE, LG&E and KU, all ARO accretion and depreciation expenses are reclassified as a regulatory asset. ARO regulatory assets associated with certain CCR projects are amortized to expense in accordance with regulatory approvals. For other AROs, at the time of retirement, the related ARO regulatory asset is offset against the associated cost of removal regulatory liability, PP&E and ARO liability.

The changes in the carrying amounts of AROs were as follows.

In addition to PPL, the other Registrants included in this filing are as follows.

(PPL Electric)

PPL Electric, headquartered in Allentown, Pennsylvania, is a wholly owned subsidiary of PPL and a regulated public utility that is an electricity transmission and distribution service provider in eastern and central Pennsylvania. PPL Electric is subject to regulation as a public utility by the PUC, and certain of its transmission activities are subject to the jurisdiction of the FERC under the Federal Power Act. PPL Electric delivers electricity in its Pennsylvania service area and provides electricity supply to retail customers in that area as a PLR under the Customer Choice Act.

(LKE)

LKE, acquired in 2010 and headquartered in Louisville, Kentucky, is a wholly owned subsidiary of PPL and a holding company that owns regulated utility operations through its subsidiaries, LG&E and KU, which constitute substantially all of LKE's assets. LG&E and KU are engaged in the generation, transmission, distribution and sale of electricity. LG&E also engages in the distribution and sale of natural gas. LG&E and KU maintain separate corporate identities and serve customers in Kentucky under their respective names. KU also serves customers in Virginia under the Old Dominion Power name.

utility by the KPSC and the VSCC, and certain of its transmission and wholesale power activities are subject to the jurisdiction of the FERC under the Federal Power Act. KU serves its Kentucky customers under the KU name and its Virginia customers under the Old Dominion Power name.

Business Strategy

(All Registrants)

PPL operates seven fully regulated, high-performing utilities. These utilities are located in the U.K., Pennsylvania and Kentucky, in constructive regulatory jurisdictions with distinct regulatory structures and customer classes. PPL believes this business portfolio positions the company well for continued success and provides earnings and dividend growth potential.

PPL's strategy, and that of the other Registrants, is to deliver best-in-sector operational performance, invest in a sustainable energy future, provide superior customer service, maintain a strong financial foundation, and engage and develop its people. PPL's business plan is designed to achieve growth by providing efficient, reliable and safe operations and strong customer service, maintaining constructive regulatory relationships and achieving timely recovery of costs. These businesses are expected to achieve strong, long-term growth in rate base in the U.S. and RAV in the U.K. Rate base growth is being driven by planned significant capital expenditures to maintain existing assets and improve system reliability and, for LKE, LG&E and KU, to comply with federal and state environmental regulations related to coal-fired electricity generation facilities.

For the U.S. businesses, central to PPL's strategy is recovering capital project costs efficiently through various rate-making mechanisms, including periodic base rate case proceedings using forward test years, annual FERC formula rate mechanisms and other regulatory agency-approved recovery mechanisms designed to limit regulatory lag. In Kentucky, the KPSC has adopted a series of regulatory mechanisms (ECR, DSM, GLT, fuel adjustment clause, and gas supply clause) and recovery on construction work-in-progress that reduce regulatory lag and provide timely recovery of and return on, as appropriate, prudently incurred costs. In addition, the KPSC requires a utility to obtain a CPCN prior to constructing a facility, unless the construction is an ordinary extension of existing facilities in the usual course of business or does not involve sufficient capital expenditures to materially affect the utility's financial condition. Although such KPSC proceedings do not directly address cost recovery issues, the KPSC, in awarding a CPCN, concludes that the public convenience and necessity require the construction of the facility on the basis that the facility is the lowest reasonable cost alternative to address the need. In Pennsylvania, the FERC transmission formula rate, DSIC mechanism, Smart Meter Rider and other recovery mechanisms operate to reduce regulatory lag and provide for timely recovery of and a return on, as appropriate, prudently incurred costs.

To manage financing costs and access to credit markets, and to fund capital expenditures, a key objective of the Registrants is to maintain their investment grade credit ratings and adequate liquidity positions. In addition, the Registrants have financial and operational risk management programs that, among other things, are designed to monitor and manage exposure to earnings and cash flow volatility, as applicable, related to changes in interest rates, foreign currency exchange rates and counterparty credit quality. To manage these risks, PPL generally uses contracts such as forwards, options and swaps. See "Financial Condition - Risk Management" below for further information.

Earnings generated by PPL's U.K. subsidiaries are subject to foreign currency translation risk. Because WPD's earnings represent such a significant portion of PPL's consolidated earnings, PPL enters into foreign currency contracts to economically hedge the value of the GBP versus the U.S. dollar. These hedges do not receive hedge accounting treatment under GAAP. See "Financial and Operational Developments - U.K. Withdrawal from European Union" for additional discussion of the U.K. earnings hedging activity.

The U.K. subsidiaries also have currency exposure to the U.S. dollar to the extent of their U.S. dollar denominated debt. To manage these risks, PPL generally uses contracts such as forwards, options and cross-currency swaps that contain characteristics of both interest rate and foreign currency exchange contracts.

As discussed above, a key component of this strategy is to maintain constructive relationships with regulators in all jurisdictions in which the Registrants operate (U.K., U.S. federal and state). This is supported by a strong culture of integrity and delivering on commitments to customers, regulators and shareowners, and a commitment to continue to improve customer service, reliability and operational efficiency.

Financial and Operational Developments

Initiation of Formal Process to Sell U.K. Utility Business (PPL)

On August 10, 2020, PPL announced that it has initiated a formal process to sell its U.K. utility business. PPL noted that there can be no assurance of any specific outcome, including whether the sale process will result in the completion of any potential transaction, the timing or terms thereof, the value or benefits that may be realized or the effect that any potential transaction will have on future financial results.

As a result of the potential sale, PPL assessed the recoverability of the assets of its U.K. utility business. PPL prepared a probability-weighted undiscounted cash flow estimate as of September 30, 2020 that considered the likelihood of the possible outcomes of the sale process, including the possibility of not selling the U.K. utility business. The resulting cash flow analysis exceeded the carrying value of the assets of the U.K. utility business. A change in the possible outcomes of the sale process could result in the carrying value of the assets of the U.K. utility business not being recoverable, which could result in an impairment in future periods. The U.K. utility business will continue to be classified as held and used until it meets the criteria to be classified as held for sale, which includes management obtaining a commitment to a plan to sell from its Board of Directors.

Should the U.K. utility business meet the criteria to be classified as held for sale in a future period, PPL will be required at that time to compare the estimated fair value of its investment in the U.K. utility business, less costs to sell, to its carrying value for impairment purposes. The measurement of PPL’s carrying value of the U.K. utility business will include the realization of accumulated other comprehensive losses, which could arise from currency translation adjustments and defined benefit plans associated with the U.K. utility business.

Outbreak of COVID-19 (All Registrants)

The continued spread of COVID-19 has led to global economic disruption and volatility in financial markets. The Registrants have taken significant steps to mitigate the potential spread of COVID-19 to our customers, suppliers and employees. PPL has successfully implemented its company-wide pandemic plan, which guides the emergency response. Business continuity and other precautionary measures have been taken to ensure we can continue to safely provide reliable electricity and gas service to our customers. The Registrants have implemented social distancing measures for all employees including work from home arrangements where possible and continue to implement strong physical and cyber security measures to ensure that systems function effectively to serve operational and remote workforce needs. The Registrants continue to monitor developments affecting their workforces and customers and will take additional actions as appropriate to respond to changing conditions and mitigate the impacts.

This is a rapidly evolving situation that could lead to extended disruption of economic activity in the Registrants’ markets for an undetermined period of time. Lock-down or closure of non-essential businesses has occurred in each of the Registrants’ service territories, which has resulted in reductions in commercial and industrial demand and an increase in residential demand for electricity service. The impact of this net reduction in load has not been material to the Registrants' year to date 2020 financial condition. The impact on future periods will depend upon various factors, including the pace and extent to which the Registrants' jurisdictions reopen their economies and community response to the reopening of businesses as well as the extent that businesses continue work from home protocols. We cannot predict these factors and therefore cannot quantify the overall impact COVID-19 will have on our 2020 results of operations.

The Registrants are committed to supporting their customers and communities and have followed federal and state mandates to suspend disconnections for non-payment and new late fees, reconnect service for customers who had previously been disconnected and develop late payment plans with customers, where appropriate. The Registrants have experienced an increase in aged accounts receivable, resulting in an increase in credit losses. See "Current Expected Credit Losses" in Note 2 to the Financial Statements for additional information. The Registrants will continue to monitor cash receipts and accounts receivable aging to determine if further increases in their allowance for uncollectible accounts are required.

At September 30, 2020, the Registrants had approximately $3.6 billion of combined unused credit facility capacity. In addition, PPL Capital Funding, PPL Electric, LG&E and KU may, subject to certain conditions, increase their syndicated credit facilities in an aggregate amount of up to $1 billion. In April 2020, PPL Capital Funding issued $1 billion in senior notes. In June 2020, KU issued $500 million of First Mortgage Bonds due 2050. In October 2020, PPL Electric issued $250 million of First Mortgage Bonds, Floating Rate Series due 2023. In October 2020, WPD (South Wales) issued £250 million of 1.625% Senior

Table of Contents

Notes due 2035. Based on available liquidity and access to capital markets, the Registrants do not anticipate a significant impact on their financial condition or liquidity, and do not foresee difficulties in accessing the capital markets in the near-term. See Note 8 to the Financial Statements for additional information.

The Registrants have assessed the fair value of their assets and liabilities and no impairment charges were required. See “Goodwill Assessment” below for additional information on the interim goodwill impairment test performed for the U.K. Regulated segment reporting unit in the first quarter of 2020.

PPL’s pension plans continue to be well-funded as its liability-driven investment strategy and active management function to mitigate investment losses resulting from market volatility.

In response to COVID-19, on March 27, 2020, President Donald Trump signed into law the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act). PPL evaluated the provisions of the CARES Act and believes there is no significant effect on its financial statements. Certain tax provisions may result in immaterial cash benefits in 2020.

To date, there has been no material impact on the Registrants’ business, financial condition, liquidity or on their supply chain as a result of COVID-19. For the three and nine months ended September 30, 2020, the following estimated changes in revenue and incremental costs incurred resulted from the impact of COVID-19:

	Increase (Reduction) in Revenue				Incremental Costs
	Three Months		Nine Months		Three Months		Nine Months
PPL	$	(33)	$	(94)	$	6	$	26
WPD	(30)		(70)		4		19
LKE	(3)		(24)		—		5
LG&E	(5)		(14)		—		2
KU	2		(10)		—		3

WPD tariffs are set to recover allowed revenues. Any under-recoveries, including the estimated amounts shown above, will be added to revenue, with interest, in future years through K-factor. See discussion of K-factor in “Item 1. Business” of PPL’s 2019 Form 10-K. The impact on revenue and incremental COVID-19 related costs were not significant at PPL Electric.

The ultimate severity or duration of the outbreak or its effects on the global economy, the capital markets, or the Registrants’ workforce, contractors, customers and suppliers is uncertain. The Registrants cannot predict the ultimate impact COVID-19 will have on their financial position, results of operations, cash flows or liquidity.

Goodwill Assessment (PPL, LKE, LG&E and KU)

The COVID-19 pandemic has disrupted the U.S. and global economies and continues to present extraordinary challenges to businesses, communities, workforces and markets. In the U.S. and throughout the world, governmental authorities have taken urgent and extensive actions to contain the spread of the virus and mitigate known or foreseeable impacts. In the Registrants’ service territories, mitigation measures have included quarantines, stay-at-home orders, travel restrictions, reduced operations or closures of businesses, schools and governmental agencies, and legislative or regulatory actions to address health or other pandemic-related concerns, all of which have the potential to adversely impact the Registrants' business and operations, especially if these measures remain in effect for a prolonged period of time. PPL’s shares have experienced volatility and a decrease in market value since the outbreak of COVID-19.

During the three month period ended March 31, 2020, PPL, LKE, LG&E and KU considered whether these events would more likely than not reduce the fair value of the Registrants’ reporting units below their carrying amounts. Based on our assessment, a quantitative impairment test was not required for the LKE, LG&E and KU reporting units, but was required for the U.K. Regulated segment reporting unit, the allocated goodwill of which was $2.5 billion at March 31, 2020. The test did not indicate impairment of the reporting unit.

Management used both discounted cash flows and market multiples, including implied RAV premiums, which required significant assumptions, to estimate the fair value of the reporting units. Significant assumptions used in the discounted cash flows include discount and growth rates, the finalization of RIIO-ED2, and projected operating and capital cash flows. Projected operating and capital cash flows are based on the internal business plans, which assume the occurrence of certain

78

Table of Contents

future events. Significant assumptions used in the market multiples include sector market performance and comparable transactions.

A high degree of judgment is required to develop estimates related to fair value conclusions. A decrease in the forecasted cash flows of 10%, an increase in the discount rate of 10%, or a 10% decrease in the market multiples would not have resulted in an impairment of goodwill for the U.K. Regulated segment reporting unit.

During the three month periods ended June 30, 2020 and September 30, 2020, no goodwill impairment triggers were identified. However, an impairment charge could occur in future periods if PPL’s share price or any of the assumptions used in determining fair value of the reporting units are negatively impacted.

U.K. Corporation Tax Rate Change (PPL)

The U.K. corporation tax rate was scheduled to be reduced from 19% to 17%, effective April 1, 2020. On March 11, 2020, the U.K. Finance Act 2020 included a cancellation of the tax rate reduction to 17%, thereby maintaining the corporation tax rate at 19%. The Finance Act 2020 was formally enacted on July 22, 2020. The primary impact of the cancellation of the corporation tax rate reduction was an increase in deferred tax liabilities and a corresponding deferred tax expense of $106 million.

U.S. Tax Reform (All Registrants)

In July 2020, the IRS issued final and new proposed regulations relating to limitations on interest deductibility for tax purposes. The Registrants will apply the final regulations beginning in the 2021 tax year. The proposed regulations will apply in the year in which the regulations are issued in final form, which is expected to be in 2021 or later. The Registrants are evaluating the final and proposed regulations, but do not expect the regulations to have a material impact on the Registrants’ financial condition or results of operations.

U.K. Withdrawal from European Union (PPL)

In March 2017, the U.K. Government invoked Article 50 (Article 50) of the Lisbon Treaty, formally beginning the two-year period for the U.K. to negotiate an agreement specifying the terms of its withdrawal from the European Union (EU), popularly referred to as Brexit. After repeated extensions, in October 2019, the EU agreed to extend the Article 50 process until January 31, 2020. Following an early general election in December 2019, which resulted in a substantial Conservative Party Parliamentary majority, the U.K. and EU Parliaments voted to approve the EU withdrawal agreement negotiated by Prime Minister Boris Johnson.

The U.K. formally left the EU on January 31, 2020, entering a transition period that is scheduled to end on December 31, 2020. During the transition period, the U.K. will seek to negotiate a free trade arrangement with the EU and also negotiate new trade terms with countries outside of the EU. The deadline for the U.K. requesting an extension to the transition period passed on June 30, 2020. Significant uncertainty continues to surround the outcome of the transition period. PPL believes that its greatest risks relate to any extended period of depressed value of the GBP or the potential further decline in the value of the GBP compared to the U.S. dollar. A decline in the value of the GBP compared to the U.S. dollar will reduce the value of WPD's earnings to PPL.

PPL has executed hedges to mitigate the foreign exchange risk to its U.K. earnings. As of September 30, 2020, PPL's foreign exchange exposure related to budgeted earnings is 100% hedged for 2020 at an average rate of $1.45 per GBP.

PPL cannot predict the impact, in either the short-term or long-term, on foreign exchange rates or PPL's financial condition that may be experienced as a result of the actions taken by the U.K. government to withdraw from the EU, although such impacts could be material.

PPL does not expect the financial condition and results of operations of WPD, itself, to change significantly as a result of Brexit. The regulatory environment and operation of WPD's businesses are not expected to change. RIIO-ED1, the current price control, with allowed revenues agreed with Ofgem runs through March 2023. The impact of a slower economy or recession on WPD would be mitigated in part because U.K. regulation provides that any reduction in the volume of electricity delivered will be recovered in allowed revenues in future periods through the K-factor adjustment. See "Item 1. Business - Segment Information - U.K. Regulated Segment" in PPL's 2019 Form 10-K for additional information on the current price control and K-factor adjustment. In addition, an increase in inflation would have a positive effect on revenues and RAV as annual inflation adjustments are applied to both revenues and RAV (and real returns are earned on inflated RAV). This impact, however, would

79

Table of Contents

be partially offset by higher operation and maintenance expenses and interest expense on index-linked debt. With respect to access to financing, WPD has substantial borrowing capacity under existing credit facilities and expects to continue to have access to all major financial markets. With respect to access to and cost of equipment and other materials, WPD management continues to review U.K. government issued advice on preparations for Brexit and has taken actions to mitigate potential increasing costs and disruption to its critical sources of supply. Additionally, less than 1% of WPD's employees are non-U.K. EU nationals and no change in their domicile is expected.

Regulatory Requirements

(All Registrants)

The Registrants cannot predict the impact that future regulatory requirements may have on their financial condition or results of operations.

(PPL, LKE, LG&E and KU)

The businesses of LKE, LG&E and KU are subject to extensive federal, state and local environmental laws, rules and regulations, including those pertaining to CCRs, GHG, and ELGs. See Notes 7, 11 and 16 to the Financial Statements for a discussion of these significant environmental matters. These and other stringent environmental requirements led PPL, LKE, LG&E and KU to retire approximately 1,200 MW of coal-fired generating plants in Kentucky since 2010.

RIIO-2 Framework (PPL)

In 2018, Ofgem issued its consultation document on the RIIO-2 framework, covering all U.K. gas and electricity transmission and distribution price controls. The current electricity distribution price control, RIIO-ED1, continues through March 31, 2023 and will not be impacted by the RIIO-2 consultation process. Later in 2018, Ofgem published its decision following its RIIO-2 framework consultation after consideration of comments received including those from WPD and PPL.

In August 2019, Ofgem published an open letter seeking views on its proposed sector specific approach on the RIIO-ED2 framework. WPD and PPL provided responses to this open letter. In December 2019, Ofgem published its decision on the RIIO-ED2 framework, thus confirming the following points in its RIIO-2 and RIIO-ED2 framework decision documents:

•RIIO-ED2 will be a five-year price control period, compared to eight years in the current RIIO-ED1 price control.

•CPI or CPIH will be used for inflation measurement in calculating both RAV and allowed returns rather than RPI.

•The baseline allowed return on equity will be set using the same methodology in all RIIO-2 sectors. The new methodology includes; (a) an equity indexation, whereby the allowed return on equity is updated to reflect changes in the risk-free rate, and (b) potentially setting the allowed return 0.5% below the expected return.

•Full debt indexation will be retained.

•The early settlement process (fast tracking) will be removed and replaced with an alternative mechanism to incentivize high-quality, rigorous and ambitious business plans.

•The Totex incentive rate will be based on a confidence level for setting baseline cost allowances.

•A new enhanced engagement model will be introduced requiring distribution companies to set up a customer engagement group to provide Ofgem with a public report of local stakeholders’ views on the companies’ business plans. Ofgem will also establish an independent RIIO-2 challenge group comprised of consumer experts to provide Ofgem with a public report on companies’ business plans.

•There will be no change to the existing depreciation policy of using economic asset lives as the basis for depreciating RAV as part of base revenue calculations. WPD is currently transitioning to 45-year asset lives for new additions in RIIO-ED1 based on Ofgem’s extensive review of asset lives in RIIO-ED1.

•A focus of RIIO-2 will be on whole-system outcomes. Ofgem intends for network companies and system operators to work together to ensure the energy system as a whole is efficient and delivers the best value to consumers. Ofgem is undertaking further work to clarify the definition of whole-system and the appropriate roles of the network companies in supporting this objective. Ofgem is still undecided on how DSO functions are to be treated. Ofgem will include a DSO reopener to reassess progress made in the establishment of DSO activities.

80

Table of Contents

On July 30, 2020 Ofgem published its consultation on the RIIO-ED2 price control methodology which Ofgem will use to apply its framework decisions listed above. Some of the key aspects in Ofgem’s consultation include:

•Proposing a suite of Net-Zero related investment and innovation mechanisms, including a Net Zero re-opener, to ensure that RIIO-ED2 is adaptable and can keep pace with changes in the wider policy and technological environment.

•Consulting on four different models for managing strategic investment to enable more flexibility within the price control and allow DNOs to adapt their investment plans to keep pace with Net Zero.

•Consulting on debt allowance proposals including the debt allowance calibration, the index used, and a possible additional cost of borrowing allowance.

•Consulting on whether the three-stage equity indexation methodology for baseline allowance returns proposed in the Gas Distribution and Transmission Draft Determination should equally apply to the ED sector and if the estimation approach for systematic risk should differ for ED2.

•Proposing to introduce a suite of reforms to define and regulate the distribution system operation. In the first instance, those reforms will apply to DNOs.

WPD and PPL continue to be fully engaged in the RIIO-ED2 process. The comment period on the July 30, 2020 consultation closed on October 1, 2020, which WPD provided a response to, and a decision on the RIIO-ED2 Sector Specific Methodology will be made in December 2020. Final Determinations for RIIO-ED2 will be made in December 2022. The RIIO-ED2 price control will come into effect on April 1, 2023. PPL cannot predict the outcome of this process or the long-term impact the final RIIO-ED2 price control will have on its financial condition or results of operations.

Challenge to PPL Electric Transmission Formula Rate Return on Equity

(PPL and PPL Electric)

On May 21, 2020, PP&L Industrial Customer Alliance (PPLICA) filed a complaint with the FERC alleging that PPL Electric's base return on equity (ROE) of 11.18% used to determine PPL Electric's formula transmission rate is unjust and unreasonable, and proposing an alternative ROE of 8.0% based on its interpretation of FERC Opinion No. 569. However, also on May 21, 2020, the FERC issued Opinion No. 569-A in response to numerous requests for rehearing of Opinion No. 569, which revised the method for analyzing base ROE. On June 10, 2020, PPLICA filed a Motion to Supplement the May 21, 2020 complaint in which PPLICA continued to allege that PPL Electric’s base ROE is unjust and unreasonable, but revised its analysis of PPL Electric's base ROE to reflect the guidance provided in Opinion No. 569-A. The amended complaint proposed an updated alternative ROE of 8.5% and also requested that the FERC preserve the original refund effective date as established by the filing of the original complaint on May 21, 2020. Several parties have filed motions to intervene, including one party who filed Comments in Support of the original complaint.

On July 10, 2020, PPL Electric filed its Answer and supporting Testimony to the PPLICA filings arguing that the FERC should deny the original and amended complaints as they are without merit and fail to demonstrate the existing base ROE is unjust and unreasonable. In addition, PPL Electric contended any refund effective date should be set for no earlier than June 10, 2020 and PPLICA's proposed replacement ROE should be rejected.

On October 15, 2020, the FERC issued an order on the PPLICA complaints which established hearing and settlement procedures, set a refund effective date of May 21, 2020 and granted the motions to intervene. PPL Electric continues to believe its ROE is just and reasonable and that it has meritorious defenses against the original and amended complaints. At this time, PPL Electric cannot predict the outcome of this matter or the range of possible losses, if any, that may be incurred. However, revenue earned from May 21, 2020 through the settlement of this matter may be subject to refund. A change of 50 basis points to the base ROE would impact PPL Electric's net income by approximately $12 million on an annual basis.

FERC Transmission Rate Filing

(PPL, LKE, LG&E and KU)

In 2018, LG&E and KU applied to the FERC requesting elimination of certain on-going credits to a sub-set of transmission customers relating to the 1998 merger of LG&E's and KU's parent entities and the 2006 withdrawal of LG&E and KU from the Midcontinent Independent System Operator, Inc. (MISO), a regional transmission operator and energy market. The application sought termination of LG&E's and KU's commitment to provide certain Kentucky municipalities mitigation for certain horizontal market power concerns arising out of the 1998 LG&E and KU merger and 2006 MISO withdrawal. The amounts at

81

Table of Contents

issue are generally waivers or credits granted to a limited number of Kentucky municipalities for either certain LG&E and KU or MISO transmission charges incurred for transmission service received. Due to the development of robust, accessible energy markets over time, LG&E and KU believe the mitigation commitments are no longer relevant or appropriate. In March 2019, the FERC granted LG&E's and KU's request to remove the ongoing credits, conditioned upon the implementation by LG&E and KU of a transition mechanism for certain existing power supply arrangements, subject to FERC review and approval. In July 2019, LG&E and KU proposed their transition mechanism to the FERC and in September 2019, the FERC rejected the proposed transition mechanism and issued a separate order providing clarifications of certain aspects of the March order. In October 2019, LG&E and KU filed requests for rehearing and clarification on the two September orders. In September 2020, FERC issued its orders in the rehearing process that modified the discussion in, and set aside portions of, the September 2019 orders including adjusting factors impacting the proposed transition mechanism. In October 2020, both LG&E and KU and other parties filed separate motions for rehearing and clarification regarding FERC’s September 2020 orders. A FERC decision on these rehearing requests is expected by November 18, 2020. Certain other petitions for review of the FERC's orders have been filed by multiple parties, including LG&E and KU, with the D.C. Circuit Court of Appeals. LG&E and KU cannot predict the outcome of these proceedings. LG&E and KU currently receive recovery of waivers and credits provided through other rate mechanisms.

(PPL and PPL Electric)

In April 2020, PPL Electric filed its annual transmission formula rate update with the FERC, reflecting a revised revenue requirement that took effect in June 2020.

Rate Case Proceedings

(PPL, LKE, LG&E and KU)

On October 23, 2020, LG&E and KU filed notices of intent with the KPSC to file applications for proposed adjustments of general electric and gas rates on or after November 25, 2020. The applications will also include requests for a CPCN to deploy Advanced Metering Infrastructure and other matters. LG&E and KU cannot predict the outcome of these potential proceedings.

(LKE and KU)

In July 2019, KU filed a request with the VSCC for an increase in annual Virginia base electricity revenues of approximately $13 million, representing an increase of 18.2%. In January 2020, KU reached a partial settlement agreement including an increase in annual Virginia base electricity revenues of $9 million effective May 1, 2020, representing an increase of 12.9%. A hearing on the settlement and certain tariff provisions was held in January 2020. On April 6, 2020, the VSCC issued an order approving the settlement and Hearing Examiner tariff provision recommendations. KU implemented the new rates on May 1, 2020.

Results of Operations

(a)The distribution price variances are primarily due to reconcilable cost recovery mechanisms approved by the PUC.

(b)The decrease for the nine months ended September 30, 2020 was primarily due to warmer weather in the first quarter of 2020, partially offset by warmer weather in the third quarter of 2020.

(c)The decrease for the three months ended September 30, 2020 was primarily the result of lower energy prices, partially offset by higher volumes of non-shopping customers and favorable weather. The decrease for the nine months ended September 30, 2020 was primarily the result of lower energy prices and unfavorable weather, partially offset by higher volumes of non-shopping customers in 2020.

(d)The increases were primarily due to returns on additional capital investments.

(e)The increase was primarily due to higher base rates, inclusive of the termination of the TCJA bill credit mechanism, effective May 1, 2019.

(f)The increase was primarily due to higher recoverable depreciation expense as a result of higher depreciation rates effective May 1, 2019.

(g)The decreases were primarily due to lower recoveries of fuel and energy purchases due to lower commodity costs.

(h)The decrease was primarily due to the termination of eight supply contracts with Kentucky municipalities on April 30, 2019.

(i)The decreases were primarily due to weather.

(j)The decreases were primarily due to COVID-19.

Fuel

Fuel decreased $17 million for the three months ended September 30, 2020 compared with 2019, primarily due to an $13 million decrease in volumes driven by weather and a $2 million decrease in commodity costs.

Fuel decreased $78 million for the nine months ended September 30, 2020 compared with 2019, primarily due to a $43 million decrease in volumes driven by weather, a $27 million decrease in commodity costs and a $9 million decrease in volumes driven by the termination of eight supply contracts with Kentucky municipalities on April 30, 2019.

Energy Purchases

Energy purchases decreased $14 million for the three months ended September 30, 2020 compared with 2019, primarily due to lower PLR prices of $21 million, partially offset by higher PLR volumes of $7 million at PPL Electric.

Energy purchases decreased $68 million for the nine months ended September 30, 2020 compared with 2019, primarily due to lower PLR prices of $54 million, partially offset by higher transmission enhancement expenses of $12 million at PPL Electric as well as a $22 million decrease due to lower commodity costs at LKE.

(a)The U.K. corporation tax rate was scheduled to be reduced from 19% to 17%, effective April 1, 2020. On March 11, 2020, the U.K. Finance Act 2020 included a cancellation of the tax rate reduction to 17%, thereby maintaining the corporation tax rate at 19%. The Finance Act 2020 was formally enacted on July 22, 2020. The primary impact of the cancellation of the corporation tax rate reduction was an increase in deferred tax liabilities and a corresponding deferred tax expense of $106 million.

(b)During the second quarter of 2019, LKE recorded a deferred income tax benefit associated with two projects placed into service that prepare a generation waste material for reuse and, as a result, qualify for a Kentucky recycling credit. The applicable credit provides tax benefits for a portion of the equipment costs for major recycling projects in Kentucky. A portion of this amount has been reserved due to insufficient Kentucky taxable income projected at LKE.

Earnings from Ongoing Operations

Management utilizes "Earnings from Ongoing Operations" as a non-GAAP financial measure that should not be considered as an alternative to net income, an indicator of operating performance determined in accordance with GAAP. PPL believes that Earnings from Ongoing Operations is useful and meaningful to investors because it provides management's view of PPL's earnings performance as another criterion in making investment decisions. In addition, PPL's management uses Earnings from Ongoing Operations in measuring achievement of certain corporate performance goals, including targets for certain executive incentive compensation. Other companies may use different measures to present financial performance.

Earnings from Ongoing Operations is adjusted for the impact of special items. Special items are presented in the financial tables on an after-tax basis with the related income taxes on special items separately disclosed. Income taxes on special items, when applicable, are calculated based on the statutory tax rate of the entity where the activity is recorded. Special items may include items such as:

• Unrealized gains or losses on foreign currency economic hedges (as discussed below).

• Gains and losses on sales of assets not in the ordinary course of business.

• Impairment charges.

• Significant workforce reduction and other restructuring effects.

• Acquisition and divestiture-related adjustments.

• Other charges or credits that are, in management's view, non-recurring or otherwise not reflective of the company's ongoing operations.

Unrealized gains or losses on foreign currency economic hedges include the changes in fair value of foreign currency contracts used to hedge GBP-denominated anticipated earnings. The changes in fair value of these contracts are recognized immediately within GAAP earnings. Management believes that excluding these amounts from Earnings from Ongoing Operations until

settlement of the contracts provides a better matching of the financial impacts of those contracts with the economic value of PPL's underlying hedged earnings. See Note 15 to the Financial Statements and "Risk Management" below for additional information on foreign currency economic activity.

PPL's Earnings from Ongoing Operations by reportable segment for the periods ended September 30 were as follows:

U.K. Regulated Segment

The U.K. Regulated segment consists of PPL Global, which primarily includes WPD's regulated electricity distribution operations, the results of hedging the translation of WPD's earnings from GBP into U.S. dollars, and certain costs, such as U.S. income taxes, administrative costs and certain acquisition-related financing costs. The U.K. Regulated segment represents 49% of PPL's Net Income for the nine months ended September 30, 2020 and 40% of PPL's assets at September 30, 2020.

Net Income and Earnings from Ongoing Operations for the periods ended September 30 include the following results.

•See "Adjusted Gross Margins - Changes in Adjusted Gross Margins" for an explanation of U.K. Adjusted Gross Margins.

•Higher other operation and maintenance expense for the nine month period primarily due to increases in various costs that were not individually significant in comparison to the prior year.

•Lower other income (expense) - net for the three and nine month periods primarily due to lower pension income.

•Lower interest expense for the three month period primarily due to interest on the index-linked bonds.

•Higher income taxes for the three month period primarily due to a $7 million impact from the tax rate change, partially offset by $6 million lower income taxes due to lower pre-tax income.

Kentucky Regulated Segment

The Kentucky Regulated segment consists primarily of LKE's regulated electricity generation, transmission and distribution operations conducted by LG&E and KU, as well as LG&E's regulated distribution and sale of natural gas. In addition, certain acquisition-related financing costs are allocated to the Kentucky Regulated segment. The Kentucky Regulated segment represents 28% of PPL's Net Income for the nine months ended September 30, 2020 and 33% of PPL's assets at September 30, 2020.

Adjusted Gross Margins

Management also utilizes the following non-GAAP financial measures as indicators of performance for its businesses:

91

Table of Contents

•"U.K. Adjusted Gross Margins" is a single financial performance measure of the electricity distribution operations of the U.K. Regulated segment. In calculating this measure, direct costs such as connection charges from National Grid, which owns and manages the electricity transmission network in England and Wales, and Ofgem license fees (recorded in "Other operation and maintenance" on the Statements of Income) are deducted from operating revenues, as they are costs passed through to customers. As a result, this measure represents the net revenues from the delivery of electricity across WPD's distribution network in the U.K. and directly related activities.

•"Kentucky Adjusted Gross Margins" is a single financial performance measure of the electricity generation, transmission and distribution operations of the Kentucky Regulated segment, as well as the Kentucky Regulated segment's distribution and sale of natural gas. In calculating this measure, fuel, energy purchases and certain variable costs of production (recorded in "Other operation and maintenance" on the Statements of Income) are deducted from operating revenues. In addition, certain other expenses, recorded in "Other operation and maintenance," "Depreciation" and "Taxes, other than income" on the Statements of Income, associated with approved cost recovery mechanisms are offset against the recovery of those expenses, which are included in revenues. These mechanisms allow for direct recovery of these expenses and, in some cases, returns on capital investments and performance incentives. As a result, this measure represents the net revenues from electricity and gas operations.

•"Pennsylvania Adjusted Gross Margins" is a single financial performance measure of the electricity transmission and distribution operations of the Pennsylvania Regulated segment. In calculating this measure, utility revenues and expenses associated with approved recovery mechanisms, including energy provided as a PLR, are offset with minimal impact on earnings. Costs associated with these mechanisms are recorded in "Energy purchases," "Other operation and maintenance" (which are primarily Act 129, Storm Damage and Universal Service program costs), "Depreciation" (which is primarily related to the Act 129 Smart Meter program) and "Taxes, other than income" (which is primarily gross receipts tax) on the Statements of Income. This measure represents the net revenues from the Pennsylvania Regulated segment's electricity delivery operations.

These measures are not intended to replace "Operating Income," which is determined in accordance with GAAP, as an indicator of overall operating performance. Other companies may use different measures to analyze and report their results of operations. Management believes these measures provide additional useful criteria to make investment decisions. These performance measures are used, in conjunction with other information, by senior management and PPL's Board of Directors to manage operations and analyze actual results compared with budget.

Changes in Adjusted Gross Margins

The following table shows Adjusted Gross Margins by PPL's reportable segment and by component, as applicable, for the periods ended September 30 as well as the change between periods. The factors that gave rise to the changes are described following the table.

U.K. Adjusted Gross Margins

U.K. Adjusted Gross Margins, excluding the impact of changes in foreign currency exchange rates, decreased for the three months ended September 30, 2020, compared with 2019, primarily due to $22 million of lower volumes, of which $30 million

(PPL)

PPL's cash provided by operating activities in 2020 increased $359 million compared with 2019.

•Net income decreased $203 million between the periods and included an increase in non-cash charges of $315 million. The increase in non-cash charges was primarily due to an increase in depreciation expense (primarily due to higher depreciation rates and additional assets placed into service, net of retirements), an increase in deferred income taxes (due to the cancellation of the U.K. corporation tax rate reduction, book versus tax plant timing differences and Federal net operating losses) and an increase in unrealized gains on derivatives, and other hedging activities, partially offset by a decrease in amortization expense.

•The $156 million increase in cash from changes in working capital was primarily due to an increase in accounts payable (primarily due to timing of disbursement of payments), a decrease in unbilled revenues (primarily due to weather), and an increase in other current liabilities, partially offset by an increase in accounts receivable (primarily due to timing of receipts) and an increase in materials and supplies (primarily due to a contract termination and subsequent guaranteed purchase of inventory from a third-party logistics firm).

•The $74 million increase in cash provided by other operating activities was driven primarily by an increase in other liabilities (primarily related to regulatory liabilities and deferral of payroll taxes).

(PPL Electric)

PPL Electric's cash provided by operating activities in 2020 increased $47 million compared with 2019.

•Net income increased $37 million between the periods and included an increase in non-cash components of $25 million. The increase in non-cash components was primarily due to an increase in depreciation expense and an increase in other expenses (primarily due to an increase in canceled projects).

•The $15 million increase in cash from changes in working capital was primarily due to a decrease in unbilled revenues (primarily due to weather), an increase in accounts payable (primarily due to timing of payments), and a decrease in

other net current assets and current liabilities, partially offset by an increase in accounts receivable (primarily due to the timing of receipts).

•The $30 million decrease in cash provided by other operating activities was driven primarily by an increase in non-current assets (primarily related to prepayments).

(LKE)

LKE's cash provided by operating activities in 2020 increased $59 million compared with 2019.

•Net income decreased $33 million between the periods and included an increase in non-cash components of $27 million. The increase in non-cash components was primarily driven by an increase in depreciation expense (primarily due to higher depreciation rates and additional assets placed into service, net of retirements), partially offset by a decrease in deferred income tax expense (primarily due to book versus tax plant timing differences).

•The increase in cash from changes in working capital was primarily driven by a decrease in unbilled revenue (primarily due to weather) and an increase in accounts payable (primarily due to timing of payments), partially offset by an increase in accounts receivable (primarily due to increase in aged receivables due to COVID-19 related disconnection moratoriums) and a decrease in interest payable (primarily due to timing of payments).

•The increase in cash provided by other operating activities was driven primarily by an increase in other liabilities (primarily related to regulatory liabilities and deferral of payroll taxes).

(LG&E)

LG&E's cash provided by operating activities in 2020 increased $2 million compared with 2019.

•Net income increased $3 million between the periods and included a decrease in non-cash components of $26 million. The decrease in non-cash components was primarily driven by a decrease in deferred income tax expense (primarily due to book versus tax plant timing differences), partially offset by an increase in depreciation expense (primarily due to higher depreciation rates and additional assets placed into service, net of retirements).

•The increase in cash from changes in working capital was primarily driven by a decrease in unbilled revenues (primarily due to weather) and net regulatory assets (primarily due to the timing of rate recovery mechanisms), partially offset by a decrease in accounts payable (primarily due to timing of payments) and an increase in accounts receivables (primarily due to increase in aged receivables due to COVID-19 related disconnection moratoriums).

•The increase in cash provided by other operating activities was driven primarily by an increase in other liabilities (primarily related to regulatory liabilities) and a decrease in ARO expenditures.

(KU)

KU's cash provided by operating activities in 2020 decreased $25 million compared with 2019.

•Net income decreased $20 million between the periods and included an increase in non-cash charges of $2 million. The increase in non-cash components was driven by an increase in depreciation expense (primarily due to higher depreciation rates and additional assets placed into service, net of retirements), partially offset by a decrease in deferred income tax expense (primarily due to book versus tax plant timing differences).

•The decrease in cash from changes in working capital was primarily driven by an increase in accounts receivable (primarily due to increase in aged receivables due to COVID-19 related disconnection moratoriums) and a decrease in other current liabilities (primarily due to timing of payments), partially offset by an increase in accounts payable (primarily due to timing of payments) and a decrease in unbilled revenues (primarily due to weather).

Investing Activities

(All Registrants)

The components of the change in cash provided by (used in) investing activities for the nine months ended September 30, 2020 compared with 2019 were as follows.

For PPL, the increase in expenditures for PP&E was due to higher project expenditures at WPD and PPL Electric, partially offset by a decrease in project expenditures at LKE, LG&E and KU. The increase in expenditures at WPD was primarily due to an increase in expenditures to enhance system reliability. The increase in expenditures at PPL Electric was primarily due to timing differences on capital spending projects related to the ongoing efforts to improve reliability and replace aging infrastructure. The decrease in expenditures at LKE was primarily due to decreased spending for environmental water projects at LG&E and KU's Trimble County plant, LG&E's Mill Creek plant and KU's Ghent plant, partially offset by spending on gas transmission projects at LG&E and spending on various other projects at LG&E and KU that are not individually significant.

(PPL Electric)

For PPL Electric, the change in "Notes receivable from affiliate" resulted from funding in 2019 of $546 million to an affiliate for general corporate purposes.

(PPL)

Equity Securities Activities

ATM

In February 2018, PPL entered into an equity distribution agreement, pursuant to which PPL may sell, from time to time, up to an aggregate of $1.0 billion of its common stock through an at-the-market offering program; including a forward sales component. The compensation paid to the selling agents by PPL may be up to 2% of the gross offering proceeds of the shares. There were no issuances under the ATM program for the nine months ended September 30, 2020.

Common Stock Dividends

In August 2020, PPL declared a quarterly common stock dividend, payable October 1, 2020, of 41.5 cents per share (equivalent to $1.66 per annum). Future dividends, declared at the discretion of the Board of Directors, will depend upon future earnings, cash flows, financial and legal requirements and other factors.

Rating Agency Actions

(All Registrants)

Moody's and S&P periodically review the credit ratings of the debt of the Registrants and their subsidiaries. Based on their respective independent reviews, the rating agencies may make certain ratings revisions or ratings affirmations.

A credit rating reflects an assessment by the rating agency of the creditworthiness associated with an issuer and particular securities that it issues. The credit ratings of the Registrants and their subsidiaries are based on information provided by the Registrants and other sources. The ratings of Moody's and S&P are not a recommendation to buy, sell or hold any securities of the Registrants or their subsidiaries. Such ratings may be subject to revisions or withdrawal by the agencies at any time and should be evaluated independently of each other and any other rating that may be assigned to the securities.

The credit ratings of the Registrants and their subsidiaries affect their liquidity, access to capital markets and cost of borrowing under their credit facilities. A downgrade in the Registrants' or their subsidiaries' credit ratings could result in higher borrowing costs and reduced access to capital markets. The Registrants and their subsidiaries have no credit rating triggers that would result in the reduction of access to capital markets or the acceleration of maturity dates of outstanding debt.

The rating agencies have taken the following actions related to the Registrants and their subsidiaries during 2020:

(PPL)

In April 2020, Moody’s and S&P assigned ratings of Baa2 and BBB+ to PPL Capital Funding’s $1 billion 4.125% Senior Notes due 2030. The notes were issued April 1, 2020.

(PPL, LKE and LG&E)

In August 2020, Moody's and S&P assigned ratings of A1 and A to the Louisville/Jefferson County Metro Government, Kentucky's $23 million 0.90% Pollution Control Revenue Bonds, 2001 Series A, due 2026, previously issued on behalf of LG&E. The bonds were remarketed September 3, 2020.

In August 2020, Moody's and S&P assigned ratings of A1 and A/A-2 to the County of Trimble, Kentucky's $125 million 1.30% Pollution Control Revenue Refunding Bonds, 2016 Series A, due 2044, previously issued on behalf of LG&E. The bonds were remarketed September 3, 2020.

(PPL, LKE and KU)

In May 2020, Moody's and S&P assigned ratings of A1 and A to KU's $500 million 3.30% First Mortgage Bonds due 2050. The bonds were issued June 3, 2020.

105

Table of Contents

(PPL and PPL Electric)

In September 2020, Moody's and S&P assigned ratings of A1 and A to PPL Electric's $250 million First Mortgage Bonds, Floating Rate Series, due 2023. The bonds were issued October 1, 2020.

In September 2020, Moody's and S&P assigned ratings of A1 and A to PEDFA's $90 million Pollution Control Revenue Refunding Bonds, Series 2008, due 2023, previously issued on behalf of PPL Electric. The bonds were remarketed October 1, 2020.

Ratings Triggers

(PPL, LKE, LG&E and KU)

Various derivative and non-derivative contracts, including contracts for the sale and purchase of electricity and fuel, commodity transportation and storage, interest rate and foreign currency instruments (for PPL), contain provisions that require the posting of additional collateral or permit the counterparty to terminate the contract, if PPL's, LKE's, LG&E's or KU's or their subsidiaries' credit rating, as applicable, were to fall below investment grade. See Note 15 to the Financial Statements for a discussion of "Credit Risk-Related Contingent Features," including a discussion of the potential additional collateral requirements for PPL, LKE and LG&E for derivative contracts in a net liability position at September 30, 2020.

Risk Management

Market Risk

(All Registrants)

See Notes 14 and 15 to the Financial Statements for information about the Registrants' risk management objectives, valuation techniques and accounting designations.

The forward-looking information presented below provides estimates of what may occur in the future, assuming certain adverse market conditions and model assumptions. Actual future results may differ materially from those presented. These are not precise indicators of expected future losses, but are rather only indicators of possible losses under normal market conditions at a given confidence level.

Interest Rate Risk

The Registrants and their subsidiaries issue debt to finance their operations, which exposes them to interest rate risk. The Registrants and their subsidiaries utilize various financial derivative instruments to adjust the mix of fixed and floating interest rates in their debt portfolios, adjust the duration of their debt portfolios and lock in benchmark interest rates in anticipation of future financing, when appropriate. Risk limits under the risk management program are designed to balance risk exposure to volatility in interest expense and changes in the fair value of the debt portfolios due to changes in the absolute level of interest rates. In addition, the interest rate risk of certain subsidiaries is potentially mitigated as a result of the existing regulatory framework or the timing of rate cases.

(a)Includes accrued interest, if applicable.

(b)Effects of adverse movements decrease assets or increase liabilities, as applicable, which could result in an asset becoming a liability. Sensitivities represent a 10% adverse movement in interest rates, except for cross-currency swaps which also includes a 10% adverse movement in foreign currency exchange rates.

(c)Changes in the fair value of these instruments are recorded in equity and reclassified into earnings in the same period during which the item being hedged affects earnings.

(d)Realized changes in the fair value of such economic hedges are recoverable through regulated rates and any subsequent changes in the fair value of these derivatives are included in regulatory assets or regulatory liabilities.

The Registrants are exposed to a potential increase in interest expense and to changes in the fair value of their debt portfolios. The estimated impact of a 10% adverse movement in interest rates on interest expense at September 30, 2020 was insignificant for PPL, PPL Electric, LKE, LG&E and KU. The estimated impact of a 10% adverse movement in interest rates on the fair value of debt at September 30, 2020 is shown below.

	10% Adverse Movement in Rates
PPL	$	611
PPL Electric	180
LKE	205
LG&E	77
KU	122

Foreign Currency Risk (PPL)

PPL is exposed to foreign currency risk primarily through investments in and earnings of U.K. affiliates. Under its risk management program, PPL is permitted to enter into financial instruments to hedge certain foreign currency exposures, including translation risk of expected earnings, firm commitments, recognized assets or liabilities, anticipated transactions, including the previously announced potential sale of its U.K. utility business, and net investments.

The following foreign currency hedges were outstanding at September 30, 2020.

	Exposure Hedged		Fair Value, Net - Asset (Liability)		Effect of a 10% Adverse Movement in Foreign Currency Exchange Rates (a)		Maturities Ranging Through
Economic hedges (b)	£	340	$	41	$	(30)	2021

(a)Effects of adverse movements decrease assets or increase liabilities, as applicable, which could result in an asset becoming a liability.

(b)To economically hedge the translation risk of expected earnings denominated in GBP.

(All Registrants)

Commodity Price Risk

PPL is exposed to commodity price risk through its domestic subsidiaries as described below.

•PPL Electric is required to purchase electricity to fulfill its obligation as a PLR. Potential commodity price risk is insignificant and mitigated through its PUC-approved cost recovery mechanism and full-requirement supply agreements to serve its PLR customers which transfer the risk to energy suppliers.

•LG&E's and KU's rates include certain mechanisms for fuel, fuel-related expenses and energy purchases. In addition, LG&E's rates include a mechanism for natural gas supply expenses. These mechanisms generally provide for timely recovery of market price fluctuations associated with these expenses.

Volumetric Risk

Volumetric risk is the risk related to the changes in volume of retail sales due to weather, economic conditions or other factors. PPL is exposed to volumetric risk through its subsidiaries as described below.

•WPD is exposed to volumetric risk which is significantly mitigated as a result of the method of regulation in the U.K. Under the RIIO-ED1 price control regulations, recovery of such exposure occurs on a two year lag. See Note 1 in PPL's 2019 Form 10-K for additional information on revenue recognition under RIIO-ED1.

•PPL Electric, LG&E and KU are exposed to volumetric risk on retail sales, mainly due to weather and other economic conditions for which there is limited mitigation between rate cases.

Foreign Currency Translation (PPL)

The value of the British pound sterling fluctuates in relation to the U.S. dollar. Changes in this exchange rate resulted in a foreign currency translation gain of $292 million for the nine months ended September 30, 2020, which primarily reflected a $477 million increase to PP&E, an $85 million increase to goodwill, a $46 million increase to other net assets, partially offset by a $229 million increase to long-term debt, a $48 million increase to long term debt due within one year, and a $39 million increase to deferred income taxes. Changes in this exchange rate resulted in a foreign currency translation loss of $369 million for the nine months ended September 30, 2019, which primarily reflected a $599 million decrease to PP&E, a $114 million decrease to goodwill and a $16 million decrease to other net assets, partially offset by a $360 million decrease to long-term debt. The impact of foreign currency translation is recorded in AOCI.

Related Party Transactions (All Registrants)

The Registrants are not aware of any material ownership interests or operating responsibility by senior management in outside partnerships, including leasing transactions with variable interest entities, or other entities doing business with the Registrants. See Note 12 to the Financial Statements for additional information on related party transactions for PPL Electric, LKE, LG&E and KU.

Acquisitions, Development and Divestitures (All Registrants)

The Registrants from time to time evaluate opportunities for potential acquisitions, divestitures and development projects. Development projects are reexamined based on market conditions and other factors to determine whether to proceed with, modify or terminate the projects. Any resulting transactions may impact future financial results. See Note 9 to the Financial Statements for information on significant activities.

Environmental Matters (All Registrants)

Extensive federal, state and local environmental laws and regulations are applicable to PPL's, PPL Electric's, LKE's, LG&E's and KU's air emissions, water discharges and the management of hazardous and solid waste, as well as other aspects of the Registrants' businesses. The costs of compliance or alleged non-compliance cannot be predicted with certainty but could be significant. In addition, costs may increase significantly if the requirements or scope of environmental laws or regulations, or similar rules, are expanded or changed. Costs may take the form of increased capital expenditures or operating and maintenance expenses, monetary fines, penalties or other restrictions. Many of these environmental law considerations are also applicable to the operations of key suppliers, or customers, such as coal producers and industrial power users, and may impact the costs for their products or their demand for the Registrants' services. Increased capital and operating costs are subject to rate recovery. PPL, PPL Electric, LKE, LG&E and KU can provide no assurances as to the ultimate outcome of future environmental or rate proceedings before regulatory authorities.

See "Environmental Matters" in Item 1. "Business" in the Registrants' 2019 Form 10-K for information about environmental laws and regulations affecting the Registrants' business. See "Legal Matters" in Note 11 to the Financial Statements for a discussion of significant environmental claims. See "Financial Condition - Liquidity and Capital Resources - Forecasted Uses of Cash - Capital Expenditures" in "Item 7. Combined Management's Discussion and Analysis of Financial Condition and Results of Operations" in the Registrants' 2019 Form 10-K for information on projected environmental capital expenditures for 2020 through 2024. See Note 16 to the Financial Statements for information related to the impacts of CCRs on AROs.

(PPL, LKE, LG&E and KU)

The information below represents an update to “Item 1. Business – Environmental Matters – Air – NAAQS” and "Item 1. Business - Environmental Matters - Water/Waste - Clean Water Act Jurisdiction" in the Registrants' 2019 Form 10-K.

NAAQS

In October 2020, the EPA released proposed revisions to the Cross-State Air Pollution Rule (CSAPR) providing for reductions in ozone season nitrogen oxide emissions for 2021 and subsequent years from sources in 12 states, including Kentucky. PPL, LKE, LG&E and KU are unable to determine the impact of the rule on operations until the rule is finalized, and certain implementation determinations are made by the EPA and Kentucky. Compliance with the NAAQS, CSAPR and related requirements may require installation of additional pollution controls or other compliance actions, the costs of which PPL, LKE, LG&E and KU believe would be subject to rate recovery.

Clean Water Act Jurisdiction

Environmental groups and others have claimed that discharges to groundwater from leaking CCR impoundments at power plants are subject to Clean Water Act permitting. A citizen suit raising such claims has been filed against KU with respect to the E.W. Brown plant, as discussed under “Legal Matters” - “E.W. Brown Environmental Claims” in Note 10 to the Financial Statements. On April 12, 2019, the EPA released regulatory clarification finding that Clean Water Act jurisdiction does not cover such discharges to groundwater. On January 23, 2020, the EPA announced a final rule modifying the jurisdictional scope of the Clean Water Act. The announced rule revises the definition of the "Waters of the United States," including a revision to exclude groundwater from the definition. In April 2020, the U.S. Supreme Court issued a ruling that Clean Water Act jurisdiction may apply to certain discharges to groundwater that result in the functional equivalent of a direct discharge to navigable waters. PPL, LKE, LG&E, and KU are unaware of any unpermitted releases from their facilities that are subject to Clean Water Act jurisdiction, but future guidance from the EPA and judicial rulings could potentially subject certain releases from CCR impoundments and landfills to additional permitting and remediation requirements, which could impose substantial costs. If any, associated costs are expected to be subject to rate recovery. PPL, LKE, LG&E and KU are unable to predict the outcome or financial impact of future regulatory proceedings and litigation.

Reference is made to "Risk Management" in "Item 2. Combined Management's Discussion and Analysis of Financial Condition and Results of Operations."

Item 4. Controls and Procedures

Although the COVID-19 pandemic prompted the Registrants to make certain procedural adjustments to accommodate an increased remote workforce, PPL’s accounting and reporting systems and functions were well prepared to perform necessary accounting and reporting activities as of September 30, 2020 and to maintain the effectiveness of its disclosure controls and procedures and internal control over financial reporting.

(a) Evaluation of disclosure controls and procedures.

The Registrants' principal executive officers and principal financial officers, based on their evaluation of the Registrants' disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934) have concluded that, as of September 30, 2020, the Registrants' disclosure controls and procedures are effective to ensure that material information relating to the Registrants and their consolidated subsidiaries is recorded, processed, summarized and reported within the time periods specified by the SEC's rules and forms, particularly during the period for which this quarterly report has been prepared. The principal officers have concluded that the disclosure controls and procedures are also effective to ensure that information required to be disclosed in reports filed under the Exchange Act is accumulated and communicated to management, including the principal executive and principal financial officers, to allow for timely decisions regarding required disclosure.

(b) Change in internal controls over financial reporting.

The Registrants' principal executive officers and principal financial officers have concluded that there were no changes in the Registrants' internal controls over financial reporting during the Registrants' third fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Registrants' internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

For information regarding legal, tax, regulatory, environmental or other administrative proceedings that became reportable events or were pending in the third quarter of 2020 see:

•"Item 3. Legal Proceedings" in each Registrant's 2019 Form 10-K; and

•Notes 6, 7 and 11 to the Financial Statements.

Item 1A. Risk Factors

There have been no material changes in the Registrants' risk factors from those disclosed in "Item 1A. Risk Factors" of the Registrants' 2019 Form 10-K, except for the following:

The COVID-19 pandemic and resultant impact on business and economic conditions could negatively affect our business.

The COVID-19 pandemic has disrupted the U.S. and global economies and continues to present extraordinary challenges to businesses, communities, workforces and markets. In the U.S. and throughout the world, governmental authorities have taken urgent and extensive actions to contain the spread of the virus and mitigate known or foreseeable impacts. In the Registrants’ service territories, mitigation measures have included quarantines, stay-at-home orders, travel restrictions, reduced operations or

111

Table of Contents

closures of businesses, schools and governmental agencies, and executive, legislative or regulatory actions to address health or other pandemic-related concerns.

Until COVID-19 is contained or an effective vaccine is identified and widely-available, the COVID-19 virus poses significant risks to the health and welfare of the Registrants’ customers, employees, contractors and suppliers, and to the conduct of their business. Mandates to stay at home, shelter in place, or quarantine and resulting lock-down or closures of non-essential businesses could reduce demand for electricity and gas, or cause shifts in demand between residential, commercial and industrial customers that could negatively impact the Registrants’ financial condition. Customers experiencing financial strain from unemployment, furloughs, or reduced work hours may not be able to pay their bills on a timely basis, which could negatively impact our liquidity. Continued economic disruption may further depress the GBP to U.S. dollar exchange rate and increase PPL's foreign exchange exposure. New or changing legislation or regulatory orders may unfavorably impact the Registrants or the utility industry generally.

All of these factors have the potential to materially and adversely affect the Registrants’ business and operations, especially if they remain in effect for a prolonged period of time. At this time, the Registrants’ cannot predict the extent to which these or other pandemic-related factors may affect their business, earnings or other financial results, as it depends on the duration and scope of the outbreak, the measures undertaken in response and other future developments, all of which are highly uncertain. In addition to the factors discussed above, investors should be aware that other COVID-19-related risks may emerge in the future and may prove to be significant. Investors should carefully consider the discussion of COVID-19 related items presented in this Quarterly Report and the risks presented in the Registrants’ Annual Report on Form 10-K for 2019, especially to the extent that the COVID-19 pandemic may exacerbate or increase those risks.

Item 4. Mine Safety Disclosures

Not applicable.

Earnings Per Share [Abstract]

Earnings Per Share

5. Earnings Per Share

(PPL)

Basic EPS is computed by dividing income available to PPL common shareowners by the weighted-average number of common shares outstanding during the applicable period. Diluted EPS is computed by dividing income available to PPL common shareowners by the weighted-average number of common shares outstanding, increased by incremental shares that would be outstanding if potentially dilutive non-participating securities were converted to common shares as calculated using the Treasury Stock Method. Incremental non-participating securities that have a dilutive impact are detailed in the table below. These dilutive securities include the PPL common stock forward sale agreements, which were settled in 2019. The forward sale

agreements were dilutive under the Treasury Stock Method to the extent the average stock price of PPL's common shares exceeded the forward sale price prescribed in the agreements.

Reconciliations of the amounts of income and shares of PPL common stock (in thousands) for the periods ended September 30 used in the EPS calculation are:

	Three Months				Nine Months

(a) The U.K. corporation tax rate was scheduled to be reduced from 19% to 17%, effective April 1, 2020. On March 11, 2020, the U.K. Finance Act 2020 included a cancellation of the tax rate reduction to 17%, thereby maintaining the corporation tax rate at 19%. The Finance Act 2020 was formally enacted on July 22, 2020. The primary impact of the cancellation of the corporation tax rate reduction was an increase in deferred tax liabilities and a corresponding deferred tax expense of $106 million.

(b) During the second quarter of 2019, LKE recorded a deferred income tax benefit associated with two projects placed into service that prepare a generation waste material for reuse and, as a result, qualify for a Kentucky recycling credit. The applicable credit provides tax benefits for a portion of the equipment costs for major recycling projects in Kentucky. A portion of this amount has been reserved due to insufficient Kentucky taxable income projected at LKE.

2020 TCJA Regulatory Update (All Registrants)

In July 2020, the IRS issued final and new proposed regulations relating to limitations on interest deductibility for tax purposes. The Registrants will apply the final regulations beginning in the 2021 tax year. The proposed regulations will apply in the year in which the regulations are issued in final form, which is expected to be in 2021 or later. The Registrants are evaluating the final and proposed regulations, but do not expect the regulations to have a material impact on the Registrants’ financial condition or results of operations.

Kentucky Activities

Rate Case Proceedings

(PPL, LKE, LG&E and KU)

On October 23, 2020, LG&E and KU filed notices of intent with the KPSC to file applications for proposed adjustments of general electric and gas rates on or after November 25, 2020. The applications will also include requests for a CPCN to deploy Advanced Metering Infrastructure and other matters. LG&E and KU cannot predict the outcome of these potential proceedings.

ECR Filings (PPL, LKE, LG&E and KU)

On March 31, 2020, LG&E and KU submitted applications to the KPSC for ECR rate treatment regarding upcoming environmental construction projects relating to the EPA's regulations addressing ELGs. The construction projects are expected to begin in 2021 and continue through 2024 and are estimated to cost approximately $405 million ($153 million at LG&E and $252 million at KU). The applications requested an authorized 9.725% return on equity with respect to these projects consistent with the 2018 Kentucky rate cases approved in April 2019. On September 29, 2020, the KPSC issued orders approving the ECR applications, permitting an authorized return on equity of 9.2% for the applicable projects.

Pennsylvania Activities 

Act 129 (PPL and PPL Electric)

The Pennsylvania Public Utility Code requires electric distribution companies, including PPL Electric, to act as a DSP, which provides electricity generation supply service to customers pursuant to a PUC-approved default service procurement plan. A DSP is able to recover the costs associated with its default service procurement plan.

In March 2020, PPL Electric filed a Petition for Approval of a new default service program and procurement plan with the PUC for the period June 1, 2021 through May 31, 2025. Hearings were held in August 2020. In October 2020, the Administrative Law Judge made a recommended decision which remains pending before the PUC. PPL Electric cannot predict the outcome of this proceeding.

Federal Matters

Challenge to PPL Electric Transmission Formula Rate Return on Equity

(PPL and PPL Electric)

On May 21, 2020, PP&L Industrial Customer Alliance (PPLICA) filed a complaint with the FERC alleging that PPL Electric's base return on equity (ROE) of 11.18% used to determine PPL Electric's formula transmission rate is unjust and unreasonable, and proposing an alternative ROE of 8.0% based on its interpretation of FERC Opinion No. 569. However, also on May 21, 2020, the FERC issued Opinion No. 569-A in response to numerous requests for rehearing of Opinion No. 569, which revised the method for analyzing base ROE. On June 10, 2020, PPLICA filed a Motion to Supplement the May 21, 2020 complaint in which PPLICA continued to allege that PPL Electric’s base ROE is unjust and unreasonable, but revised its analysis of PPL Electric's base ROE to reflect the guidance provided in Opinion No. 569-A. The amended complaint proposed an updated alternative ROE of 8.5% and also requested that the FERC preserve the original refund effective date as established by the filing of the original complaint on May 21, 2020. Several parties have filed motions to intervene, including one party who filed Comments in Support of the original complaint.

On July 10, 2020, PPL Electric filed its Answer and supporting Testimony to the PPLICA filings arguing that the FERC should deny the original and amended complaints as they are without merit and fail to demonstrate the existing base ROE is unjust and unreasonable. In addition, PPL Electric contended any refund effective date should be set for no earlier than June 10, 2020 and PPLICA's proposed replacement ROE should be rejected.

On October 15, 2020, the FERC issued an order on the PPLICA complaints which established hearing and settlement procedures, set a refund effective date of May 21, 2020 and granted the motions to intervene. PPL Electric continues to believe its ROE is just and reasonable and that it has meritorious defenses against the original and amended complaints. At this time, PPL Electric cannot predict the outcome of this matter or the range of possible losses, if any, that may be incurred. However, revenue earned from May 21, 2020 through the settlement of this matter may be subject to refund. A change of 50 basis points to the base ROE would impact PPL Electric's net income by approximately $12 million on an annual basis.

FERC Transmission Rate Filing

(PPL, LKE, LG&E and KU)

In 2018, LG&E and KU applied to the FERC requesting elimination of certain on-going credits to a sub-set of transmission customers relating to the 1998 merger of LG&E's and KU's parent entities and the 2006 withdrawal of LG&E and KU from the Midcontinent Independent System Operator, Inc. (MISO), a regional transmission operator and energy market. The application sought termination of LG&E's and KU's commitment to provide certain Kentucky municipalities mitigation for certain horizontal market power concerns arising out of the 1998 LG&E and KU merger and 2006 MISO withdrawal. The amounts at issue are generally waivers or credits granted to a limited number of Kentucky municipalities for either certain LG&E and KU or MISO transmission charges incurred for transmission service received. Due to the development of robust, accessible energy markets over time, LG&E and KU believe the mitigation commitments are no longer relevant or appropriate. In March 2019, the FERC granted LG&E's and KU's request to remove the ongoing credits, conditioned upon the implementation by LG&E and KU of a transition mechanism for certain existing power supply arrangements, subject to FERC review and approval. In July 2019, LG&E and KU proposed their transition mechanism to the FERC and in September 2019, the FERC rejected the proposed transition mechanism and issued a separate order providing clarifications of certain aspects of the March order. In October 2019, LG&E and KU filed requests for rehearing and clarification on the two September orders. In September 2020, FERC issued its orders in the rehearing process that modified the discussion in, and set aside portions of, the September 2019 orders including adjusting factors impacting the proposed transition mechanism. In October 2020, both LG&E and KU and other parties filed separate motions for rehearing and clarification regarding FERC’s September 2020 orders. A FERC decision on these rehearing requests is expected by November 18, 2020. Certain other petitions for review of the FERC's orders have been filed by multiple parties, including LG&E and KU, with the D.C. Circuit Court of Appeals. LG&E and KU cannot predict the outcome of these proceedings. LG&E and KU currently receive recovery of waivers and credits provided through other rate mechanisms.

(PPL and PPL Electric)

In April 2020, PPL Electric filed its annual transmission formula rate update with the FERC, reflecting a revised revenue requirement that took effect in June 2020.

Other

Purchase of Receivables Program (PPL and PPL Electric)

In accordance with a PUC-approved purchase of accounts receivable program, PPL Electric purchases certain accounts receivable from alternative electricity suppliers at a discount, which reflects a provision for credit losses. The alternative electricity suppliers have no continuing involvement or interest in the purchased accounts receivable. Accounts receivable that are acquired are initially recorded at fair value on the date of acquisition. During the three and nine months ended September 30, 2020, PPL Electric purchased $303 million and $854 million of accounts receivable from alternative suppliers. During the three and nine months ended September 30, 2019, PPL Electric purchased $308 million and $927 million of accounts receivable from alternative suppliers.

For the periods ended September 30, PPL Services allocated the following net periodic defined benefit costs to PPL Electric, and LKE allocated the following net periodic defined benefit costs to LG&E and KU:

	Three Months				Nine Months
	2020		2019		2020		2019
PPL Electric	$	3	$	3	$	9	$	8
LG&E (a)	9		1		14		3
KU	4		—		5		—

(a)    Allocations to LG&E increased in 2020 primarily due to the merger of plans sponsored by LKE and LG&E effective January 1, 2020 into the LG&E and KU Pension Plan.

The non-service cost components of net periodic defined benefit costs (credits) (interest cost, expected return on plan assets, amortization of prior service cost and amortization of actuarial gain and loss) are presented in "Other Income (Expense) - net" on the Statements of Income. See Note 13 for additional information.

Cash Flows - U.S. Pension Plans

(PPL, LKE and LG&E)

During the nine months ended September 30, 2020, LKE contributed $22 million to its pension plans. LKE anticipates making $23 million in additional contributions in the fourth quarter of 2020.

Legal Matters

(All Registrants)

PPL and its subsidiaries are involved in legal proceedings, claims and litigation in the ordinary course of business. PPL and its subsidiaries cannot predict the outcome of such matters, or whether such matters may result in material liabilities, unless otherwise noted.

Talen Litigation (PPL)

Background

In September 2013, one of PPL's former subsidiaries, PPL Montana entered into an agreement to sell its hydroelectric generating facilities. In June 2014, PPL and PPL Energy Supply, the parent company of PPL Montana, entered into various definitive agreements with affiliates of Riverstone to spin off PPL Energy Supply and ultimately combine it with Riverstone's competitive power generation businesses to form a stand-alone company named Talen Energy. In November 2014, after executing the spinoff agreements but prior to the closing of the spinoff transaction, PPL Montana closed the sale of its hydroelectric generating facilities. Subsequently, on June 1, 2015, the spinoff of PPL Energy Supply was completed. Following the spinoff transaction, PPL had no continuing ownership interest in or control of PPL Energy Supply. In connection with the spinoff transaction, PPL Montana became Talen Montana, LLC (Talen Montana), a subsidiary of Talen Energy. Talen Energy Marketing also became a subsidiary of Talen Energy as a result of the June 2015 spinoff of PPL Energy Supply. Talen Energy has owned and operated both Talen Montana and Talen Energy Marketing since the spinoff. At the time of the spinoff, affiliates of Riverstone acquired a 35% ownership interest in Talen Energy. Riverstone subsequently acquired the remaining interests in Talen Energy in a take private transaction in December 2016.

Talen Montana Retirement Plan and Talen Energy Marketing, LLC, Individually and on Behalf of All Others Similarly Situated v. PPL Corporation et al.

On October 29, 2018, Talen Montana Retirement Plan and Talen Energy Marketing filed a putative class action complaint on behalf of current and contingent creditors of Talen Montana who allegedly suffered harm or allegedly will suffer reasonably foreseeable harm as a result of a November 2014 distribution of proceeds from the sale of then-PPL Montana's hydroelectric generating facilities. The action was filed in the Sixteenth Judicial District of the State of Montana, Rosebud County, against PPL and certain of its affiliates and current and former officers and directors (Talen Putative Class Action). Plaintiff asserts claims for, among other things, fraudulent transfer, both actual and constructive; recovery against subsequent transferees; civil conspiracy; aiding and abetting tortious conduct; and unjust enrichment. Plaintiff is seeking avoidance of the purportedly fraudulent transfer, unspecified damages, including punitive damages, the imposition of a constructive trust, and other relief. In December 2018, PPL removed the Talen Putative Class Action from the Sixteenth Judicial District of the State of Montana to the United States District Court for the District of Montana, Billings Division (MT Federal Court). In January 2019, the plaintiff moved to remand the Talen Putative Class Action back to state court, and dismissed without prejudice all current and former PPL Corporation directors from the case. In September 2019, the MT Federal Court granted plaintiff's motion to remand the case back to state court. Although, the PPL defendants petitioned the Ninth Circuit Court of Appeals to grant an appeal of the remand decision, in November 2019, the Ninth Circuit Court of Appeals denied that request and in December 2019, Talen Montana Retirement Plan filed a Second Amended Complaint in the Sixteenth Judicial District of the State of Montana, Rosebud County, which removed Talen Energy Marketing as a plaintiff. In January 2020, PPL defendants filed a motion to dismiss the Second Amended Complaint or, in the alternative, to stay the proceedings pending the resolution of the below mentioned Delaware Action. The Court held a hearing on June 24, 2020 regarding the motion to dismiss. On September 11, 2020, the Court granted PPL defendants' alternative Motion for a Stay of the proceedings.

PPL Corporation et al. vs. Riverstone Holdings LLC, Talen Energy Corporation et al.

On November 30, 2018, PPL, certain PPL affiliates, and certain current and former officers and directors (PPL plaintiffs) filed a complaint in the Court of Chancery of the State of Delaware seeking various forms of relief against Riverstone, Talen Energy and certain of their affiliates (Delaware Action), in response to and as part of the defense strategy for an action filed by Talen Montana, LLC (the Talen Direct Action, since dismissed) and the Talen Putative Class Action described above (together, the Montana Actions) originally filed in Montana state court in October 2018. In the complaint, the PPL plaintiffs ask the Delaware Court of Chancery for declaratory and injunctive relief. This includes a declaratory judgment that, under the separation agreement governing the spinoff of PPL Energy Supply, all related claims that arise must be heard in Delaware; that the statute of limitations in Delaware and the spinoff agreement bar these claims at this time; that PPL is not liable for the claims in either the Talen Direct Action or the Talen Putative Class Action as PPL Montana was solvent at all relevant times; and that the separation agreement requires that Talen Energy indemnify PPL for all losses arising from the debts of Talen Montana, among other things. PPL's complaint also seeks damages against Riverstone for interfering with the separation agreement and against Riverstone affiliates for breach of the implied covenant of good faith and fair dealing. The complaint was subsequently amended on January 11, 2019 and March 20, 2019, to include, among other things, claims related to indemnification with respect to the Montana Actions, request a declaration that the Montana Actions are time-barred under the spinoff agreements, and allege additional facts to support the tortious interference claim. In April 2019, the defendants filed motions to dismiss the amended complaint. In July 2019, the Court heard oral arguments from the parties regarding the motions to dismiss, and in October 2019, the Delaware Court of Chancery issued an opinion sustaining all of the PPL plaintiffs' claims except for the claim for breach of implied covenant of good faith and fair dealing. As a result of the dismissal of the Talen Direct Action in December 2019, in January 2020, Talen Energy filed a new motion to dismiss five of the remaining eight claims in the amended complaint. The Court heard oral argument on the motion to dismiss on May 28, 2020, and on June 22, 2020, issued an opinion denying the motion in its entirety. Discovery is proceeding, and a trial has been scheduled for June 2021.

With respect to each of the Talen-related matters described above, PPL believes that the 2014 distribution of proceeds was made in compliance with all applicable laws and that PPL Montana was solvent at all relevant times. Additionally, the agreements entered into in connection with the spinoff, which PPL and affiliates of Talen Energy and Riverstone negotiated and executed prior to the 2014 distribution, directly address the treatment of the proceeds from the sale of PPL Montana's hydroelectric generating facilities; in those agreements, Talen Energy and Riverstone definitively agreed that PPL was entitled to retain the proceeds.

PPL believes that it has meritorious defenses to the claims made in the Talen Putative Class Action and intends to continue to vigorously defend against this action. The Talen Putative Class Action and the Delaware Action are both in early stages of litigation; at this time, PPL cannot predict the outcome of these matters or estimate the range of possible losses, if any, that PPL might incur as a result of the claims, although they could be material.

(PPL, LKE and LG&E)

Cane Run Environmental Claims

In December 2013, six residents, on behalf of themselves and others similarly situated, filed a class action complaint against LG&E and PPL in the U.S. District Court for the Western District of Kentucky (U.S. District Court) alleging violations of the Clean Air Act, RCRA, and common law claims of nuisance, trespass and negligence. In July 2014, the U.S. District Court

dismissed the RCRA claims and all but one Clean Air Act claim, but declined to dismiss the common law tort claims. In February 2017, the U.S. District Court dismissed PPL as a defendant and dismissed the final federal claim against LG&E, and in April 2017, issued an Order declining to exercise supplemental jurisdiction on the state law claims dismissing the case in its entirety. In June 2017, the plaintiffs filed a class action complaint in Jefferson County, Kentucky Circuit Court, against LG&E alleging state law nuisance, negligence and trespass tort claims. The plaintiffs seek compensatory and punitive damages for alleged property damage due to purported plant emissions on behalf of a class of residents within one to three miles of the plant. On January 8, 2020, the Jefferson Circuit Court issued an order denying the plaintiffs’ request for class certification. On January 14, 2020, the plaintiffs filed a notice of appeal in the Kentucky Court of Appeals with oral arguments scheduled for November 17, 2020. PPL, LKE and LG&E cannot predict the outcome of this matter and an estimate or range of possible losses cannot be determined.

(PPL, LKE and KU)

E.W. Brown Environmental Claims

In July 2017, the Kentucky Waterways Alliance and the Sierra Club filed a citizen suit complaint against KU in the U.S. District Court for the Eastern District of Kentucky (U.S. District Court) alleging discharges at the E.W. Brown plant in violation of the Clean Water Act and the plant's water discharge permit, and alleging contamination that may present an imminent and substantial endangerment in violation of the RCRA. The plaintiffs' suit relates to prior notices of intent to file a citizen suit submitted in October and November 2015 and October 2016. These plaintiffs sought injunctive relief ordering KU to take all actions necessary to comply with the Clean Water Act and RCRA, including ceasing the discharges in question, abating effects associated with prior discharges and eliminating the alleged imminent and substantial endangerment. These plaintiffs also sought assessment of civil penalties and an award of litigation costs and attorney fees. In December 2017, the U.S. District Court issued an Order dismissing the Clean Water Act and RCRA complaints against KU in their entirety. In January 2018, the plaintiffs appealed the dismissal Order to the U.S. Court of Appeals for the Sixth Circuit. In September 2018, the U.S. Court of Appeals for the Sixth Circuit issued its ruling affirming the lower court's decision to dismiss the Clean Water Act claims but reversing its dismissal of the RCRA claims against KU and remanding the latter to the U.S. District Court. In October 2018, KU filed a petition for rehearing to the U.S. Court of Appeals for the Sixth Circuit regarding the RCRA claims. In November 2018, the U.S. Court of Appeals for the Sixth Circuit denied KU's petition for rehearing regarding the RCRA claims. In January 2019, KU filed an answer to plaintiffs’ complaint in the U.S. District Court. A trial has been scheduled to begin in February 2021. PPL, LKE and KU cannot predict the outcome of these matters and an estimate or range of possible losses cannot be determined.

KU is undertaking extensive remedial measures at the E.W. Brown plant including work preparing for closure of the former ash pond, implementation of a groundwater remedial action plan and performance of a corrective action plan including aquatic study of adjacent surface waters and risk assessment. The aquatic study and risk assessment are being undertaken pursuant to a 2017 agreed Order with the Kentucky Energy and Environment Cabinet (KEEC). KU conducted sampling of Herrington Lake in 2017 and 2018. In June 2019, KU submitted to the KEEC the required aquatic study and risk assessment, conducted by an independent third-party consultant, finding that discharges from the E.W. Brown plant have not had any significant impact on Herrington Lake and that the water in the lake is safe for recreational use and meets safe drinking water standards. However, until the KEEC assesses the study and issues any regulatory determinations, PPL, LKE and KU are unable to determine whether additional remedial measures will be required at the E.W. Brown plant.

Air

Sulfuric Acid Mist Emissions (PPL, LKE and LG&E)

In June 2016, the EPA issued a notice of violation under the Clean Air Act alleging that LG&E violated applicable rules relating to sulfuric acid mist emissions at its Mill Creek plant. The notice alleges failure to install proper controls, failure to operate the facility consistent with good air pollution control practice, and causing emissions exceeding applicable requirements or constituting a nuisance or endangerment. LG&E believes it has complied with applicable regulations during the relevant time period. On July 31, 2020, the U.S. Department of Justice filed a complaint in the U.S. District Court for the Western District of Kentucky alleging violations specified in the EPA notice of violation and seeking civil penalties and injunctive relief. In October 2020, LG&E filed a motion to dismiss the complaint. In October 2020, the U.S. Department of Justice indicated plans to file an amended complaint, as authorized by an agreed order of the court and parties. PPL, LKE and LG&E are unable to predict the outcome of this matter or the potential impact on operations of the Mill Creek plant, including increased capital or operating costs, and potential civil penalties or remedial measures, if any. An estimate or range of possible losses cannot be determined.

Water/Waste

(PPL, LKE, LG&E and KU)

ELGs

In 2015, the EPA finalized ELGs for wastewater discharge permits for new and existing steam electricity generating facilities. These guidelines require deployment of additional control technologies providing physical, chemical and biological treatment and mandate operational changes including "no discharge" requirements for certain wastewaters. The implementation date for individual generating stations was to be determined by the states on a case-by-case basis according to criteria provided by the

EPA. Legal challenges to the final rule were consolidated before the U.S. Court of Appeals for the Fifth Circuit. In April 2017, the EPA announced that it would grant petitions for reconsideration of the rule. In September 2017, the EPA issued a rule to postpone the compliance date for certain requirements. On October 13, 2020, the EPA published final revisions to its best available technology standards for certain wastewaters and potential extensions to compliance dates. The rule will be implemented by the states or applicable permitting authorities in the course of their normal permitting activities. LG&E and KU have developed responsive compliance strategies and schedules. Certain aspects of these compliance plans and estimates relate to developments in state water quality standards, which are separate from the ELG rule or its implementation. Certain costs are included in the Registrants' capital plans and expected to be recovered from customers through rate recovery mechanisms, but additional costs and recovery will depend on further regulatory developments at the state level. See Note 7 for additional information regarding LG&E’s and KU’s applications for ECR rate treatment of construction costs relating to regulations addressing ELGs.

CCRs

In 2015, the EPA issued a final rule governing management of CCRs which include fly ash, bottom ash and sulfur dioxide scrubber wastes. The CCR Rule imposes extensive new requirements for certain CCR impoundments and landfills, including public notifications, location restrictions, design and operating standards, groundwater monitoring and corrective action requirements, and closure and post-closure care requirements, and specifies restrictions relating to the beneficial use of CCRs. In July 2018, the EPA issued a final rule extending the deadline for closure of certain impoundments and adopting other substantive changes. In August 2018, the D.C. Circuit Court of Appeals vacated and remanded portions of the CCR Rule. In December 2019, the EPA addressed the deficiencies identified by the court and proposed amendments to change the closure deadline. In August 2020, the EPA published a final rule extending the deadline to initiate closure to April 11, 2021, while providing for certain extensions. EPA has announced that additional amendments to the rule are planned. PPL, LKE, LG&E and KU are unable to predict the outcome of the ongoing litigation and rulemaking or potential impacts on current LG&E and KU compliance plans. The Registrants are currently finalizing closure plans and schedules.

In January 2017, Kentucky issued a new state rule relating to CCR management, effective May 2017, aimed at reflecting the requirements of the federal CCR rule. As a result of a subsequent legal challenge, in January 2018, the Franklin County, Kentucky Circuit Court issued an opinion invalidating certain procedural elements of the rule. LG&E and KU presently operate their facilities under continuing permits authorized under the former program and do not currently anticipate material impacts as a result of the judicial ruling. The Kentucky Energy and Environmental Cabinet has announced it intends to propose new state rules aimed at addressing procedural deficiencies identified by the court and providing the regulatory framework necessary for operation of the state program in lieu of the federal CCR Rule. Associated costs are expected to be subject to rate recovery.

LG&E and KU received KPSC approval for a compliance plan providing for the closure of impoundments at the Mill Creek, Trimble County, E.W. Brown, and Ghent stations, and construction of process water management facilities at those plants. In addition to the foregoing measures required for compliance with the federal CCR rule, KU also received KPSC approval for its plans to close impoundments at the retired Green River, Pineville and Tyrone plants to comply with applicable state law. Since 2017, LG&E and KU have commenced closure of many of the subject impoundments and have completed closure of some of their smaller impoundments. LG&E and KU expect to commence closure of the remaining impoundments no later than April 2021. LG&E and KU generally expect to complete impoundment closures within five years of commencement, although a longer period may be required to complete closure of some facilities. Associated costs are expected to be subject to rate recovery.

In connection with the final CCR rule, LG&E and KU recorded adjustments to existing AROs beginning in 2015 and continue to record adjustments as required. See Note 16 for additional information. Further changes to AROs, current capital plans or operating costs may be required as estimates are refined based on closure developments, groundwater monitoring results, and regulatory or legal proceedings. Costs relating to this rule are subject to rate recovery.

Superfund and Other Remediation

PPL Electric, LG&E and KU are potentially responsible for investigating and remediating contamination under the federal Superfund program and similar state programs. Actions are under way at certain sites including former coal gas manufacturing plants in Pennsylvania and Kentucky previously owned or operated by, or currently owned by predecessors or affiliates of, PPL Electric, LG&E and KU. PPL Electric is potentially responsible for a share of clean-up costs at certain sites including the

Columbia Gas Plant site and the Brodhead site. Clean-up actions have been or are being undertaken at all of these sites, the costs of which have not been and are not expected to be significant to PPL Electric.

As of September 30, 2020 and December 31, 2019, PPL Electric had a recorded liability of $10 million representing its best estimate of the probable loss to be incurred to remediate the sites identified above. Depending on the outcome of investigations at identified sites where investigations have not begun or been completed, or developments at sites for which information is incomplete, additional costs of remediation could be incurred. PPL Electric, LG&E and KU lack sufficient information about such additional sites to estimate any potential liability or range of reasonably possible losses, if any, related to these sites. Such costs, however, are not currently expected to be significant.

The EPA is evaluating the risks associated with polycyclic aromatic hydrocarbons and naphthalene, chemical by-products of coal gas manufacturing. As a result, individual states may establish stricter standards for water quality and soil cleanup, that could require several PPL subsidiaries to take more extensive assessment and remedial actions at former coal gas manufacturing plants. PPL, PPL Electric, LKE, LG&E and KU cannot estimate a range of possible losses, if any, related to these matters.

Regulatory Issues (All Registrants)

See Note 7 for information on regulatory matters related to utility rate regulation.

Electricity - Reliability Standards

The NERC is responsible for establishing and enforcing mandatory reliability standards (Reliability Standards) regarding the bulk electric system in North America. The FERC oversees this process and independently enforces the Reliability Standards.

The Reliability Standards have the force and effect of law and apply to certain users of the bulk electric system, including electric utility companies, generators and marketers. Under the Federal Power Act, the FERC may assess civil penalties for certain violations.

PPL Electric, LG&E and KU monitor their compliance with the Reliability Standards and self-report or self-log potential violations of applicable reliability requirements whenever identified, and submit accompanying mitigation plans, as required. The resolution of a small number of potential violations is pending. Penalties incurred to date have not been significant. Any Regional Reliability Entity determination concerning the resolution of violations of the Reliability Standards remains subject to the approval of the NERC and the FERC.

In the course of implementing their programs to ensure compliance with the Reliability Standards by those PPL affiliates subject to the standards, certain other instances of potential non-compliance may be identified from time to time. The Registrants cannot predict the outcome of these matters, and an estimate or range of possible losses cannot be determined.

Other

Labor Union Agreements

(LKE and KU)

In August 2020, KU and the United Steelworkers of America ratified a three-year labor agreement through August 2023. The agreement covers approximately 48 employees. The terms of the new labor agreement are not expected to have a significant impact on the financial results of LKE or KU.

(LKE and LG&E)

On November 4, 2020, LG&E and the IBEW reached an agreement in principle regarding a new three-year collective bargaining agreement. The proposed agreement is to be submitted to a vote of IBEW union members during early November 2020. The agreement covers approximately 640 employees. The terms of the proposed labor agreement are not expected to have a significant impact on the financial results of LKE or LG&E. The Registrants cannot predict the ultimate outcome of this matter.

Guarantees and Other Assurances

(All Registrants)

In the normal course of business, the Registrants enter into agreements that provide financial performance assurance to third parties on behalf of certain subsidiaries. Such agreements include, for example, guarantees, stand-by letters of credit issued by financial institutions and surety bonds issued by insurance companies. These agreements are entered into primarily to support or enhance the creditworthiness attributed to a subsidiary on a stand-alone basis or to facilitate the commercial activities in which these subsidiaries engage.

(PPL)

PPL fully and unconditionally guarantees all of the debt securities of PPL Capital Funding.

(All Registrants)

The table below details guarantees provided as of September 30, 2020. "Exposure" represents the estimated maximum potential amount of future payments that could be required to be made under the guarantee. The probability of expected payment/performance under each of these guarantees is remote except for "WPD guarantee of pension and other obligations of unconsolidated entities," for which PPL has a total recorded liability of $5 million at September 30, 2020 and December 31, 2019. For reporting purposes, on a consolidated basis, all guarantees of PPL Electric, LKE, LG&E and KU also apply to PPL, and all guarantees of LG&E and KU also apply to LKE.

	Exposure at September 30, 2020			Expiration Date
PPL
WPD indemnifications for entities in liquidation and sales of assets	$	10	(a)	2022
WPD guarantee of pension and other obligations of unconsolidated entities	90		(b)
LKE
Indemnification of lease termination and other divestitures	200		(c)	2021
LG&E and KU
LG&E and KU obligation of shortfall related to OVEC			(d)

(a)Indemnification to the liquidators and certain others for existing liabilities or expenses or liabilities arising during the liquidation process. The indemnifications are limited to distributions made from the subsidiary to its parent either prior or subsequent to liquidation or are not explicitly stated in the agreements. The indemnifications generally expire two to seven years subsequent to the date of dissolution of the entities. The exposure noted only includes those cases where the agreements provide for specific limits.

In connection with their sales of various businesses, WPD and its affiliates have provided the purchasers with indemnifications that are standard for such transactions, including indemnifications for certain pre-existing liabilities and environmental and tax matters or have agreed to continue their obligations under existing third-party guarantees, either for a set period of time following the transactions or upon the condition that the purchasers make reasonable efforts to terminate the guarantees. Additionally, WPD and its affiliates remain secondarily responsible for lease payments under certain leases that they have assigned to third parties.

(b)Relates to certain obligations of discontinued or modified electric associations that were guaranteed at the time of privatization by the participating members. Costs are allocated to the members and can be reallocated if an existing member becomes insolvent. At September 30, 2020, WPD has recorded an estimated discounted liability for which the expected payment/performance is probable. Neither the expiration date nor the maximum amount of potential payments for certain obligations is explicitly stated in the related agreements, and as a result, the exposure has been estimated.

(c)LKE provides certain indemnifications covering the due and punctual payment, performance and discharge by each party of its respective obligations. The most comprehensive of these guarantees is the LKE guarantee covering operational, regulatory and environmental commitments and indemnifications made by WKE under a 2009 Transaction Termination Agreement. This guarantee has a term of 12 years ending July 2021, and a maximum exposure of $200 million exclusive of certain items such as government fines and penalties that may exceed the maximum. Additionally, LKE has indemnified various third parties related to historical obligations for other divested subsidiaries and affiliates. The indemnifications vary by entity and the maximum exposures range from being capped at the sale price to no specified maximum. LKE could be required to perform on these indemnifications in the event of covered losses or liabilities being claimed by an indemnified party. LKE cannot predict the ultimate outcomes of the various indemnification scenarios, but does not expect such outcomes to result in significant losses above the amounts recorded.

(d)Pursuant to the OVEC power purchase contract, LG&E and KU are obligated to pay for their share of OVEC's excess debt service, post-retirement and decommissioning costs, as well as any shortfall from amounts included within a demand charge designed and expected to cover these costs over the term of the contract. LKE's proportionate share of OVEC's outstanding debt was $105 million at September 30, 2020, consisting of LG&E's share of $73 million and KU's share of $32 million. The maximum exposure and the expiration date of these potential obligations are not presently determinable. See "Energy Purchase Commitments" in Note 13 in PPL's, LKE's, LG&E's and KU's 2019 Form 10-K for additional information on the OVEC power purchase contract.

In March 2018, a sponsor with a 4.85% pro-rata share of OVEC obligations filed for bankruptcy under Chapter 11 and, in August 2018, received a rejection order for the OVEC power purchase contract in the bankruptcy proceeding. OVEC and other entities challenged the contract rejection, the

bankruptcy plan confirmation and regulatory aspects of the plan in various forums. In May 2020, OVEC and the relevant sponsor announced a settlement resolving all disputed matters in the bankruptcy and other proceedings, including providing that the sponsor will withdraw its request to reject the power purchase agreement. The settlement was implemented in July 2020. Periodically, OVEC and certain of its sponsors, including LG&E and KU, may consider certain potential additional credit support actions to preserve OVEC's access to credit markets, including establishing or continuing debt reserve accounts or other changes involving OVEC's existing short and long-term debt.

The Registrants provide other miscellaneous guarantees through contracts entered into in the normal course of business. These guarantees are primarily in the form of indemnification or warranties related to services or equipment and vary in duration. The amounts of these guarantees often are not explicitly stated, and the overall maximum amount of the obligation under such guarantees cannot be reasonably estimated. Historically, no significant payments have been made with respect to these types of guarantees and the probability of payment/performance under these guarantees is remote.

PPL, on behalf of itself and certain of its subsidiaries, maintains insurance that covers liability assumed under contract for bodily injury and property damage. The coverage provides maximum aggregate coverage of $225 million. This insurance may be applicable to obligations under certain of these contractual arrangements.

Risks and Uncertainties (All Registrants)

The COVID-19 pandemic has disrupted the U.S. and global economies and continues to present extraordinary challenges to businesses, communities, workforces and markets. In the U.S. and throughout the world, governmental authorities have taken urgent and extensive actions to contain the spread of the virus and mitigate known or foreseeable impacts. In the Registrants’ service territories, mitigation measures have included quarantines, stay-at-home orders, travel restrictions, reduced operations or closures of businesses, schools and governmental agencies, and legislative or regulatory actions to address health or other pandemic-related concerns, all of which have the potential to adversely impact the Registrants' business and operations, especially if these measures remain in effect for a prolonged period of time.

To date, the Registrants have not experienced a significant impact on their business, results of operations, financial condition, liquidity, operations or on their supply chain as a result of COVID-19; however, the duration and severity of the outbreak and its ultimate effects on the global economy, the financial markets, or the Registrants’ workforce, customers and suppliers are uncertain. A protracted slowdown of broad sectors of the economy, prolonged or pervasive restrictions on businesses and their workforces, or significant changes in legislation or regulatory policy to address the COVID-19 pandemic all present significant risks to the Registrants. These or other unpredictable events resulting from the pandemic could further reduce customer demand for electricity and gas, impact the Registrants’ employees and supply chains, result in an increase in certain costs, delay payments or increase bad debts, or result in changes in the fair value of their assets and liabilities, which could materially and adversely affect the Registrants’ business, results of operations, financial condition or liquidity.

Support Costs (PPL Electric, LKE, LG&E and KU)

PPL Services, PPL EU Services and LKS provide PPL, PPL Electric, LKE, their respective subsidiaries, including LG&E and KU, and each other with administrative, management and support services. For all services companies, the costs of directly assignable and attributable services are charged to the respective recipients as direct support costs. General costs that cannot be directly assigned or attributed to a specific entity are allocated and charged to the respective recipients as indirect support costs. PPL Services and PPL EU Services use a three-factor methodology that includes the applicable recipients' invested capital, operation and maintenance expenses and number of employees to allocate indirect costs. PPL Services may also use a ratio of overall direct and indirect costs or a weighted average cost ratio. LKS bases its indirect allocations on the subsidiaries' number of employees, total assets, revenues, number of customers and/or other statistical information. PPL Services, PPL EU Services and LKS charged the following amounts for the periods ended September 30, including amounts applied to accounts that are further distributed between capital and expense on the books of the recipients, based on methods that are believed to be reasonable.

	Three Months				Nine Months
	2020		2019		2020		2019
PPL Electric from PPL Services	$	11	$	14	$	37	$	43
LKE from PPL Services	6		6		19		20
PPL Electric from PPL EU Services	44		38		126		112
LG&E from LKS	43		37		125		112
KU from LKS	45		42		132		126

In addition to the charges for services noted above, LKS makes payments on behalf of LG&E and KU for fuel purchases and other costs for products or services provided by third parties. LG&E and KU also provide services to each other and to LKS. Billings between LG&E and KU relate to labor and overheads associated with union and hourly employees performing work for the other company, charges related to jointly-owned generating units and other miscellaneous charges.

Fair Value Disclosures [Abstract]

Fair Value Measurements

14. Fair Value Measurements

(All Registrants)

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). A market approach (generally, data from market transactions), an income approach (generally, present value techniques and option-pricing models) and/or a cost approach (generally, replacement cost) are used to measure the fair value of an asset or liability, as appropriate. These valuation approaches incorporate inputs such as observable, independent market data and/or unobservable data that management believes are predicated on the assumptions market participants would use to price an asset or liability. These inputs may incorporate, as applicable, certain risks such as nonperformance risk, which includes credit risk. The fair value of a group of financial assets and liabilities is measured on a net basis. See Note 1 in each Registrant's 2019 Form 10-K for information on the levels in the fair value hierarchy.

Special Use Funds

(PPL)

The special use funds are investments restricted for paying active union employee medical costs. In May 2018, PPL received a favorable private letter ruling from the IRS permitting a transfer of excess funds from the PPL Bargaining Unit Retiree Health Plan VEBA to a new subaccount within the VEBA to be used to pay medical claims of active bargaining unit employees. The funds are invested primarily in commingled debt and equity funds measured at NAV and are classified as investments in equity securities. Changes in fair value of the funds are recorded to the Statements of Income.

Price Risk Management Assets/Liabilities - Interest Rate Swaps/Foreign Currency Contracts/Cross-Currency Swaps

(PPL, LKE, LG&E and KU)

To manage interest rate risk, PPL, LKE, LG&E and KU use interest rate contracts such as forward-starting swaps, floating-to-fixed swaps and fixed-to-floating swaps. To manage foreign currency exchange risk, PPL uses foreign currency contracts such as forwards, options and cross-currency swaps that contain characteristics of both interest rate and foreign currency contracts. An income approach is used to measure the fair value of these contracts, utilizing readily observable inputs, such as forward interest rates (e.g., LIBOR and government security rates) and forward foreign currency exchange rates (e.g., GBP), as well as inputs that may not be observable, such as credit valuation adjustments. In certain cases, market information cannot practicably be obtained to value credit risk and therefore internal models are relied upon. These models use projected probabilities of default and estimated recovery rates based on historical observances. When the credit valuation adjustment is significant to the overall valuation, the contracts are classified as Level 3.

Financial Instruments Not Recorded at Fair Value (All Registrants)

The carrying amounts of long-term debt on the Balance Sheets and their estimated fair values are set forth below. Long-term debt is classified as Level 2. The effect of third-party credit enhancements is not included in the fair value measurement.

Derivative Instruments and Hedging Activities

15. Derivative Instruments and Hedging Activities

Risk Management Objectives

(All Registrants)

PPL has a risk management policy approved by the Board of Directors to manage market risk associated with commodities, interest rates on debt issuances and foreign exchange (including price, liquidity and volumetric risk) and credit risk (including non-performance risk and payment default risk). The Risk Management Committee, comprised of senior management and chaired by the Senior Director-Risk Management, oversees the risk management function. Key risk control activities designed to ensure compliance with the risk policy and detailed programs include, but are not limited to, credit review and approval, validation of transactions, verification of risk and transaction limits, value-at-risk analyses (VaR, a statistical model that attempts to estimate the value of potential loss over a given holding period under normal market conditions at a given confidence level) and the coordination and reporting of the Enterprise Risk Management program.

Market Risk

Market risk includes the potential loss that may be incurred as a result of price changes associated with a particular financial or commodity instrument as well as market liquidity and volumetric risks. Forward contracts, futures contracts, options, swaps and structured transactions are utilized as part of risk management strategies to minimize unanticipated fluctuations in earnings caused by changes in commodity prices, interest rates and foreign currency exchange rates. Many of these contracts meet the definition of a derivative. All derivatives are recognized on the Balance Sheets at their fair value, unless NPNS is elected.

The following summarizes the market risks that affect PPL and its subsidiaries.

Interest Rate Risk

•PPL and its subsidiaries are exposed to interest rate risk associated with forecasted fixed-rate and existing floating-rate debt issuances. PPL and WPD hold over-the-counter cross currency swaps to limit exposure to market fluctuations on interest and principal payments from changes in foreign currency exchange rates and interest rates. PPL, LKE and LG&E utilize over-the-counter interest rate swaps to limit exposure to market fluctuations on floating-rate debt. PPL, WPD, LKE, LG&E and KU utilize forward starting interest rate swaps to hedge changes in benchmark interest rates, when appropriate, in connection with future debt issuances.

•PPL and its subsidiaries are exposed to interest rate risk associated with debt securities and derivatives held by defined benefit plans. This risk is significantly mitigated to the extent that the plans are sponsored at, or sponsored on behalf of, the regulated domestic utilities and for certain plans at WPD due to the recovery methods in place.

Foreign Currency Risk (PPL)

•PPL is exposed to foreign currency exchange risk primarily associated with its investments in and earnings of U.K. affiliates.

(All Registrants)

Commodity Price Risk

PPL is exposed to commodity price risk through its domestic subsidiaries as described below.

•PPL Electric is required to purchase electricity to fulfill its obligation as a PLR. Potential commodity price risk is insignificant and mitigated through its PUC-approved cost recovery mechanism and full-requirement supply agreements to serve its PLR customers which transfer the risk to energy suppliers.

•LG&E's and KU's rates include certain mechanisms for fuel, fuel-related expenses and energy purchases. In addition, LG&E's rates include a mechanism for natural gas supply expenses. These mechanisms generally provide for timely recovery of market price fluctuations associated with these expenses.

Volumetric Risk

Volumetric risk is the risk related to the changes in volume of retail sales due to weather, economic conditions or other factors. PPL is exposed to volumetric risk through its subsidiaries as described below.

•WPD is exposed to volumetric risk which is significantly mitigated as a result of the method of regulation in the U.K. Under the RIIO-ED1 price control regulations, recovery of such exposure occurs on a two year lag. See Note 1 in PPL's 2019 Form 10-K for additional information on revenue recognition under RIIO-ED1.

•PPL Electric, LG&E and KU are exposed to volumetric risk on retail sales, mainly due to weather and other economic conditions for which there is limited mitigation between rate cases.

Equity Securities Price Risk

•PPL and its subsidiaries are exposed to equity securities price risk associated with the fair value of the defined benefit plans' assets. This risk is significantly mitigated at the regulated domestic utilities and for certain plans at WPD due to the recovery methods in place.

•PPL is exposed to equity securities price risk from future stock sales and/or purchases.

Credit Risk

Credit risk is the potential loss that may be incurred due to a counterparty's non-performance.

PPL is exposed to credit risk from "in-the-money" interest rate and foreign currency derivatives with financial institutions, as well as additional credit risk through certain of its subsidiaries, as discussed below.

In the event a supplier of PPL Electric, LG&E or KU defaults on its obligation, those Registrants would be required to seek replacement power or replacement fuel in the market. In general, subject to regulatory review or other processes, appropriate incremental costs incurred by these entities would be recoverable from customers through applicable rate mechanisms, thereby mitigating the financial risk for these entities.

PPL and its subsidiaries have credit policies in place to manage credit risk, including the use of an established credit approval process, daily monitoring of counterparty positions and the use of master netting agreements or provisions. These agreements generally include credit mitigation provisions, such as margin, prepayment or collateral requirements. PPL and its subsidiaries may request additional credit assurance, in certain circumstances, in the event that the counterparties' credit ratings fall below investment grade, their tangible net worth falls below specified percentages or their exposures exceed an established credit limit.

Master Netting Arrangements (PPL, LKE, LG&E and KU)

Net derivative positions on the balance sheets are not offset against the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) under master netting arrangements.

PPL had a $9 million and $14 million obligation to return cash collateral under master netting arrangements at September 30, 2020 and December 31, 2019.

LKE, LG&E and KU had no obligation to return cash collateral under master netting arrangements at September 30, 2020 and December 31, 2019.

PPL, LKE and LG&E posted $1 million of cash collateral under master netting arrangements at September 30, 2020. KU had no obligation to post cash collateral under master netting arrangements at September 30, 2020. PPL, LKE, LG&E and KU had no obligation to post cash collateral under master netting arrangements at December 31, 2019.

See "Offsetting Derivative Instruments" below for a summary of derivative positions presented in the balance sheets where a right of setoff exists under these arrangements.

Interest Rate Risk

(All Registrants)

PPL and its subsidiaries issue debt to finance their operations, which exposes them to interest rate risk. A variety of financial derivative instruments are utilized to adjust the mix of fixed and floating interest rates in their debt portfolios, adjust the duration of the debt portfolios and lock in benchmark interest rates in anticipation of future financing, when appropriate. Risk limits under PPL's risk management program are designed to balance risk exposure to volatility in interest expense and changes in the fair value of the debt portfolio due to changes in benchmark interest rates. In addition, the interest rate risk of certain subsidiaries is potentially mitigated as a result of the existing regulatory framework or the timing of rate cases.

Cash Flow Hedges (PPL)

Interest rate risks include exposure to adverse interest rate movements for outstanding variable rate debt and for future anticipated financings. Financial interest rate swap contracts that qualify as cash flow hedges may be entered into to hedge floating interest rate risk associated with both existing and anticipated debt issuances. At September 30, 2020, PPL held an aggregate notional value in interest rate swap contracts of £126 million (approximately $168 million based on spot rates) that mature in 2035 to hedge interest payments on WPD's £250 million debt issuance which occurred in October 2020.

At September 30, 2020, PPL held an aggregate notional value in cross-currency interest rate swap contracts of $702 million that range in maturity from 2021 through 2028 to hedge the interest payments and principal of WPD's U.S. dollar-denominated senior notes.

Cash flow hedges are discontinued if it is no longer probable that the original forecasted transaction will occur by the end of the originally specified time period and any amounts previously recorded in AOCI are reclassified into earnings once it is determined that the hedged transaction is not probable of occurring.

For the three and nine months ended September 30, 2020 and 2019, PPL had no cash flow hedges reclassified into earnings associated with discontinued cash flow hedges.

At September 30, 2020, the amount of accumulated net unrecognized after-tax gains (losses) on qualifying derivatives expected to be reclassified into earnings during the next 12 months is insignificant. Amounts are reclassified as the hedged interest expense is recorded.

Economic Activity (PPL, LKE and LG&E)

LG&E enters into interest rate swap contracts that economically hedge interest payments. Because realized gains and losses from the swaps, including terminated swap contracts, are recoverable through regulated rates, any subsequent changes in fair value of these derivatives are included in regulatory assets or liabilities until they are realized as interest expense. Realized gains and losses are recognized in "Interest Expense" on the Statements of Income at the time the underlying hedged interest

expense is recorded. At September 30, 2020, LG&E held contracts with a notional amount of $147 million that range in maturity through 2033.

Foreign Currency Risk (PPL)

PPL is exposed to foreign currency risk, primarily through investments in and earnings of U.K. affiliates. PPL has adopted a foreign currency risk management program designed to hedge certain foreign currency exposures, including firm commitments, recognized assets or liabilities, anticipated transactions, including the previously announced potential sale of its U.K. utility business, and net investments. In addition, PPL enters into financial instruments to protect against foreign currency translation risk of expected GBP earnings.

Net Investment Hedges

PPL enters into foreign currency contracts on behalf of a subsidiary to protect the value of a portion of its net investment in WPD. There were no contracts outstanding at September 30, 2020.

At September 30, 2020 and December 31, 2019, PPL had $33 million and $32 million of accumulated net investment hedge after tax gains (losses) that were included in the foreign currency translation adjustment component of AOCI.

Economic Activity

PPL enters into foreign currency contracts on behalf of a subsidiary to economically hedge GBP-denominated anticipated earnings. At September 30, 2020, the total exposure hedged by PPL was approximately £340 million (approximately $482 million based on contracted rates). These contracts have termination dates ranging from October 2020 through July 2021.

Accounting and Reporting

(All Registrants)

All derivative instruments are recorded at fair value on the Balance Sheet as an asset or liability unless NPNS is elected. NPNS contracts include certain full requirement purchase contracts and other physical purchase contracts. Changes in the fair value of derivatives not designated as NPNS are recognized in earnings unless specific hedge accounting criteria are met and designated as such, except for the changes in fair values of LG&E's interest rate swaps that are recognized as regulatory assets or regulatory liabilities. See Note 7 for amounts recorded in regulatory assets and regulatory liabilities at September 30, 2020 and December 31, 2019.

See Note 1 in each Registrant's 2019 Form 10-K for additional information on accounting policies related to derivative instruments.

Offsetting Derivative Instruments

PPL, LKE, LG&E and KU or certain of their subsidiaries have master netting arrangements in place and also enter into agreements pursuant to which they purchase or sell certain energy and other products. Under the agreements, upon termination of the agreement as a result of a default or other termination event, the non-defaulting party typically would have a right to set off amounts owed under the agreement against any other obligations arising between the two parties (whether under the agreement or not), whether matured or contingent and irrespective of the currency, place of payment or place of booking of the obligation.

PPL, LKE, LG&E and KU have elected not to offset derivative assets and liabilities and not to offset net derivative positions against the right to reclaim cash collateral pledged (an asset) or the obligation to return cash collateral received (a liability) under derivatives agreements. The table below summarizes the derivative positions presented in the balance sheets where a right of setoff exists under these arrangements and related cash collateral received or pledged.

Credit Risk-Related Contingent Features

Certain derivative contracts contain credit risk-related contingent features which, when in a net liability position, would permit the counterparties to require the transfer of additional collateral upon a decrease in the credit ratings of PPL, LKE, LG&E and KU or certain of their subsidiaries. Most of these features would require the transfer of additional collateral or permit the counterparty to terminate the contract if the applicable credit rating were to fall below investment grade. Some of these features also would allow the counterparty to require additional collateral upon each downgrade in credit rating at levels that remain above investment grade. In either case, if the applicable credit rating were to fall below investment grade, and assuming no assignment to an investment grade affiliate were allowed, most of these credit contingent features require either immediate payment of the net liability as a termination payment or immediate and ongoing full collateralization on derivative instruments in net liability positions.

Additionally, certain derivative contracts contain credit risk-related contingent features that require adequate assurance of performance be provided if the other party has reasonable concerns regarding the performance of PPL's, LKE's, LG&E's and KU's obligations under the contracts. A counterparty demanding adequate assurance could require a transfer of additional collateral or other security, including letters of credit, cash and guarantees from a creditworthy entity. This would typically involve negotiations among the parties. However, amounts disclosed below represent assumed immediate payment or immediate and ongoing full collateralization for derivative instruments in net liability positions with "adequate assurance" features.

(PPL, LKE and LG&E)

At September 30, 2020, derivative contracts in a net liability position that contain credit risk-related contingent features, collateral posted on those positions and the related effect of a decrease in credit ratings below investment grade are summarized as follows:

16. Asset Retirement Obligations

(PPL, LKE, LG&E and KU)

PPL's, LKE's, LG&E's and KU's ARO liabilities are primarily related to CCR closure costs. See Note 11 for information on the CCR rule. LG&E also has AROs related to natural gas mains and wells. LG&E's and KU's transmission and distribution lines largely operate under perpetual property easement agreements, which do not generally require restoration upon removal of the property. Therefore, no material AROs are recorded for transmission and distribution assets. For LKE, LG&E and KU, all ARO accretion and depreciation expenses are reclassified as a regulatory asset. ARO regulatory assets associated with certain CCR projects are amortized to expense in accordance with regulatory approvals. For other AROs, at the time of retirement, the related ARO regulatory asset is offset against the associated cost of removal regulatory liability, PP&E and ARO liability.

The changes in the carrying amounts of AROs were as follows.

PPL's, LKE's, LG&E's and KU's ARO liabilities are primarily related to CCR closure costs. See Note 11 for information on the CCR rule. LG&E also has AROs related to natural gas mains and wells. LG&E's and KU's transmission and distribution lines largely operate under perpetual property easement agreements, which do not generally require restoration upon removal of the property. Therefore, no material AROs are recorded for transmission and distribution assets. For LKE, LG&E and KU, all ARO accretion and depreciation expenses are reclassified as a regulatory asset. ARO regulatory assets associated with certain CCR projects are amortized to expense in accordance with regulatory approvals. For other AROs, at the time of retirement, the related ARO regulatory asset is offset against the associated cost of removal regulatory liability, PP&E and ARO liability.

The changes in the carrying amounts of AROs were as follows.

Interim Financial Statements [Abstract]

Interim Financial Statements

1. Interim Financial Statements

(All Registrants)

Capitalized terms and abbreviations appearing in the unaudited combined notes to condensed financial statements are defined in the glossary. Dollars are in millions, except per share data, unless otherwise noted. The specific Registrant to which disclosures are applicable is identified in parenthetical headings in italics above the applicable disclosure or within the applicable disclosure for each Registrant's related activities and disclosures. Within combined disclosures, amounts are disclosed for any Registrant when significant.

The accompanying unaudited condensed financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all of the information and footnote disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation in accordance with GAAP are reflected in the condensed financial statements. All adjustments are of a normal recurring nature, except as otherwise disclosed. Each Registrant's Balance Sheet at December 31, 2019 is derived from that Registrant's 2019 audited Balance Sheet. The financial statements and notes thereto should be read in conjunction with the financial statements and notes contained in each Registrant's 2019 Form 10-K. The results of operations for the three and nine months ended September 30, 2020 are not necessarily indicative of the results to be expected for the full year ending December 31, 2020 or other future periods, because results for interim periods can be disproportionately influenced by various factors, developments and seasonal variations.

The following accounting policy disclosures represent updates to Note 1 in each Registrant's 2019 Form 10-K and should be read in conjunction with those disclosures.

Restricted Cash and Cash Equivalents (PPL and PPL Electric)

Reconciliation of Cash, Cash Equivalents and Restricted Cash

The following provides a reconciliation of Cash, Cash Equivalents and Restricted Cash reported within the Balance Sheets that sum to the total of the same amounts shown on the Statements of Cash Flows:

	PPL				PPL Electric
	September 30, 2020		December 31, 2019		September 30, 2020		December 31, 2019
Cash and cash equivalents	$	746	$	815	$	26	$	262

Restricted cash - noncurrent (a)	20		18		—		—
Total Cash, Cash Equivalents and Restricted Cash	$	769	$	836	$	28	$	264

(a)Bank deposits and other cash equivalents that are restricted by agreement or that have been clearly designated for a specific purpose are classified as restricted cash. On the Balance Sheets, the current portion of restricted cash is included in "Other current assets," while the noncurrent portion is included in "Other noncurrent assets."

Current Expected Credit Losses

(All Registrants)

Financing receivable collectability is evaluated using a combination of factors, including past due status based on contractual terms, trends in write-offs and the age of the receivable. Specific events, such as bankruptcies, are also considered when applicable. Adjustments to the reserve for credit losses are made when necessary based on the results of analysis, the aging of receivables and historical and industry trends. The Registrants periodically evaluate the impact of observable external factors on the collectability of the financing receivables to determine if adjustments to the reserve for credit losses should be made based on current conditions or reasonable and supportable forecasts.

Accounts receivable are written off in the period in which the receivable is deemed uncollectible.

(PPL and PPL Electric)

PPL Electric has identified one class of financing receivables, “accounts receivable-customer”, which includes financing receivables for all billed and unbilled sales with residential and non-residential customers. All other financing receivables are classified as other. Within the credit loss model for the residential customer accounts receivables, customers are disaggregated based on their projected propensity to pay, which is derived from historical trends and the current activity of the individual customer accounts. Conversely, the non-residential customer accounts receivables are not further segmented due to the varying nature of the individual customers, which lack readily identifiable risk characteristics for disaggregation.

(PPL, LKE, LG&E and KU)

LKE, LG&E and KU have identified one class of financing receivables, “accounts receivable-customer”, which includes financing receivables for all billed and unbilled sales with customers. All other financing receivables are classified as other.

(All Registrants)

The following table shows changes in the allowance for credit losses for the nine months ended September 30, 2020:

	Balance at Beginning of Period (a)		Charged to Income		Deductions (b)		Balance at End of Period
PPL
Accounts Receivable - Customer and Unbilled Revenue	$	30	$	22	$	9	$	43
Other (c)	27		2		—		29

	Balance at Beginning of Period (a)		Charged to Income		Deductions (b)		Balance at End of Period

(a)Reflects cumulative-effect adjustment upon adoption of current expected credit loss guidance.

(b)Primarily related to uncollectible accounts receivable written off.

(c)Primarily related to receivables at WKE, which are fully reserved.

Asset Impairment (Excluding Investments)

(PPL, LKE, LG&E and KU)

PPL, LKE, LG&E and KU review goodwill for impairment at the reporting unit level annually or more frequently when events or circumstances indicate that the carrying amount of a reporting unit may be greater than the unit's fair value. PPL's, LKE's, LG&E's and KU's reporting units are primarily at the operating segment level.

During the three month period ended March 31, 2020, PPL, LKE, LG&E and KU considered whether the economic events associated with COVID-19, which resulted in PPL’s shares experiencing volatility and a decrease in market value, would more likely than not reduce the fair value of the Registrants’ reporting units below their carrying amounts. See "Risks and Uncertainties" in Note 11 for additional information about COVID-19. Based on our assessment, a quantitative impairment test was not required for the LKE, LG&E and KU reporting units, but was required for the U.K. Regulated segment reporting unit, the allocated goodwill of which was $2.5 billion at March 31, 2020. The test did not indicate impairment of the reporting unit.

During the three month periods ended June 30, 2020 and September 30, 2020, no goodwill impairment triggers were identified. However, an impairment charge could occur in future periods if PPL’s share price or any of the assumptions used in determining fair value of the reporting units are negatively impacted.

(PPL)

On August 10, 2020, PPL announced that it is initiating a formal process to sell its U.K. utility business. As a result of the potential sale, PPL assessed the recoverability of the assets of its U.K. utility business. See Note 9 for additional information.

New Accounting Guidance Adopted

(All Registrants)

Accounting for Financial Instrument Credit Losses

Effective January 1, 2020, the Registrants adopted accounting guidance, using a modified retrospective approach, that requires the use of a current expected credit loss (CECL) model for the measurement of credit losses on financial instruments within the scope of the guidance, which includes accounts receivable. The CECL model requires an entity to measure credit losses using historical information, current information and reasonable and supportable forecasts of future events, rather than the incurred loss impairment model required under previous GAAP. The adoption of this guidance did not have a material impact on the Registrants.

Accounting for Implementation Costs in a Cloud Computing Service Arrangement

Effective January 1, 2020, the Registrants prospectively adopted accounting guidance that requires a customer in a cloud computing hosting arrangement that is a service contract to capitalize implementation costs consistent with internal-use software guidance for non-service arrangements. The guidance requires these capitalized implementation costs to be amortized over the term of the hosting arrangement to the statement of income line item where the service arrangement costs are recorded. The guidance also prescribes the financial statement classification of the capitalized implementation costs and cash flows associated with the arrangement. The adoption of this guidance did not have a material impact on the Registrants.

(PPL, LKE, LG&E and KU)

Simplifying the Test for Goodwill Impairment

Effective January 1, 2020, the Registrants adopted accounting guidance that simplifies the test for goodwill impairment by eliminating the second step of the quantitative test. The second step of the quantitative test required a calculation of the implied fair value of goodwill, which was determined in the same manner as the amount of goodwill in a business combination. Under the new guidance, the fair value of a reporting unit will be compared with the carrying value and an impairment charge will be recognized if the carrying amount exceeds the fair value of the reporting unit. The adoption of this guidance did not have a material impact on the Registrants.

(c)Includes wholesale power and transmission revenues. LG&E and KU amounts include intercompany power sales and transmission revenues, which are eliminated upon consolidation at LKE.

(d)In the fourth quarter of 2019, management deemed it appropriate to present the revenue offset associated with network integration transmission service (NITS) as distribution revenue rather than transmission revenue.

As discussed in Note 2 in PPL's 2019 Form 10-K, PPL segments its business by geographic location. Revenues from external customers for each segment/geographic location are reconciled to revenues from contracts with customers in the footnotes to the tables above. PPL Electric's revenues from contracts with customers are further disaggregated by distribution and transmission, which were $407 million and $174 million for the three months ended September 30, 2020 and $1.2 billion and $497 million for the nine months ended September 30, 2020. PPL Electric's revenue from contracts with customers disaggregated by distribution and transmission were $477 million and $112 million for the three months ended September 30, 2019 and $1.4 billion and $318 million for the nine months ended September 30, 2019.

Contract receivables from customers are primarily included in "Accounts receivable - Customer" and "Unbilled revenues" on the Balance Sheets.

The following table shows the accounts receivable and unbilled revenues balances that were impaired for the periods ended September 30.

	Three Months				Nine Months
	2020		2019		2020		2019

The following table shows the balances and certain activity of contract liabilities resulting from contracts with customers.

	PPL		PPL Electric		LKE		LG&E		KU
Contract liabilities at December 31, 2019	$	44	$	21	$	9	$	5	$	4
Contract liabilities at September 30, 2020	40		18		9		5		4

Revenue recognized during the nine months ended September 30, 2019 that was included in the contract liability balance at December 31, 2018	31		11		9		5		4

Contract liabilities result from recording contractual billings in advance for customer attachments to the Registrants' infrastructure and payments received in excess of revenues earned to date. Advanced billings for customer attachments are recognized as revenue ratably over the billing period. Payments received in excess of revenues earned to date are recognized as revenue as services are delivered in subsequent periods.

At September 30, 2020, PPL had $40 million of performance obligations attributable to Corporate and Other that have not been satisfied. Of this amount, PPL expects to recognize approximately $40 million within the next 12 months.

(PPL)

On August 10, 2020, PPL announced that it has initiated a formal process to sell its U.K. utility business. PPL noted that there can be no assurance of any specific outcome, including whether the sale process will result in the completion of any potential transaction, the timing or terms thereof, the value or benefits that may be realized or the effect that any potential transaction will have on future financial results.

As a result of the potential sale, PPL assessed the recoverability of the assets of its U.K. utility business. PPL prepared a probability-weighted undiscounted cash flow estimate as of September 30, 2020 that considered the likelihood of the possible outcomes of the sale process, including the possibility of not selling the U.K. utility business. The resulting cash flow analysis exceeded the carrying value of the assets of the U.K. utility business. A change in the possible outcomes of the sale process could result in the carrying value of the assets of the U.K. utility business not being recoverable, which could result in an impairment in future periods. The U.K. utility business will continue to be classified as held and used until it meets the criteria to be classified as held for sale, which includes management obtaining a commitment to a plan to sell from its Board of Directors.

Should the U.K. utility business meet the criteria to be classified as held for sale in a future period, PPL will be required at that time to compare the estimated fair value of its investment in the U.K. utility business, less costs to sell, to its carrying value for impairment purposes. The measurement of PPL’s carrying value of the U.K. utility business will include the realization of accumulated other comprehensive losses, which could arise from currency translation adjustments and defined benefit plans associated with the U.K. utility business.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]

Credit Loss, Financial Instrument [Text Block]

Current Expected Credit Losses

(All Registrants)

Financing receivable collectability is evaluated using a combination of factors, including past due status based on contractual terms, trends in write-offs and the age of the receivable. Specific events, such as bankruptcies, are also considered when applicable. Adjustments to the reserve for credit losses are made when necessary based on the results of analysis, the aging of receivables and historical and industry trends. The Registrants periodically evaluate the impact of observable external factors on the collectability of the financing receivables to determine if adjustments to the reserve for credit losses should be made based on current conditions or reasonable and supportable forecasts.

Accounts receivable are written off in the period in which the receivable is deemed uncollectible.

(PPL and PPL Electric)

PPL Electric has identified one class of financing receivables, “accounts receivable-customer”, which includes financing receivables for all billed and unbilled sales with residential and non-residential customers. All other financing receivables are classified as other. Within the credit loss model for the residential customer accounts receivables, customers are disaggregated based on their projected propensity to pay, which is derived from historical trends and the current activity of the individual customer accounts. Conversely, the non-residential customer accounts receivables are not further segmented due to the varying nature of the individual customers, which lack readily identifiable risk characteristics for disaggregation.

(PPL, LKE, LG&E and KU)

LKE, LG&E and KU have identified one class of financing receivables, “accounts receivable-customer”, which includes financing receivables for all billed and unbilled sales with customers. All other financing receivables are classified as other.

New Accounting Pronouncements, Policy

New Accounting Guidance Adopted

(All Registrants)

Accounting for Financial Instrument Credit Losses

Effective January 1, 2020, the Registrants adopted accounting guidance, using a modified retrospective approach, that requires the use of a current expected credit loss (CECL) model for the measurement of credit losses on financial instruments within the scope of the guidance, which includes accounts receivable. The CECL model requires an entity to measure credit losses using historical information, current information and reasonable and supportable forecasts of future events, rather than the incurred loss impairment model required under previous GAAP. The adoption of this guidance did not have a material impact on the Registrants.

Accounting for Implementation Costs in a Cloud Computing Service Arrangement

Effective January 1, 2020, the Registrants prospectively adopted accounting guidance that requires a customer in a cloud computing hosting arrangement that is a service contract to capitalize implementation costs consistent with internal-use software guidance for non-service arrangements. The guidance requires these capitalized implementation costs to be amortized over the term of the hosting arrangement to the statement of income line item where the service arrangement costs are recorded. The guidance also prescribes the financial statement classification of the capitalized implementation costs and cash flows associated with the arrangement. The adoption of this guidance did not have a material impact on the Registrants.

(PPL, LKE, LG&E and KU)

Simplifying the Test for Goodwill Impairment

Effective January 1, 2020, the Registrants adopted accounting guidance that simplifies the test for goodwill impairment by eliminating the second step of the quantitative test. The second step of the quantitative test required a calculation of the implied fair value of goodwill, which was determined in the same manner as the amount of goodwill in a business combination. Under the new guidance, the fair value of a reporting unit will be compared with the carrying value and an impairment charge will be recognized if the carrying amount exceeds the fair value of the reporting unit. The adoption of this guidance did not have a material impact on the Registrants.

(a) The U.K. corporation tax rate was scheduled to be reduced from 19% to 17%, effective April 1, 2020. On March 11, 2020, the U.K. Finance Act 2020 included a cancellation of the tax rate reduction to 17%, thereby maintaining the corporation tax rate at 19%. The Finance Act 2020 was formally enacted on July 22, 2020. The primary impact of the cancellation of the corporation tax rate reduction was an increase in deferred tax liabilities and a corresponding deferred tax expense of $106 million.

(b) During the second quarter of 2019, LKE recorded a deferred income tax benefit associated with two projects placed into service that prepare a generation waste material for reuse and, as a result, qualify for a Kentucky recycling credit. The applicable credit provides tax benefits for a portion of the equipment costs for major recycling projects in Kentucky. A portion of this amount has been reserved due to insufficient Kentucky taxable income projected at LKE.

Commitments and Contingencies Disclosure [Abstract]

Guarantees

The table below details guarantees provided as of September 30, 2020.

	Exposure at September 30, 2020			Expiration Date
PPL
WPD indemnifications for entities in liquidation and sales of assets	$	10	(a)	2022
WPD guarantee of pension and other obligations of unconsolidated entities	90		(b)
LKE
Indemnification of lease termination and other divestitures	200		(c)	2021
LG&E and KU
LG&E and KU obligation of shortfall related to OVEC			(d)

(a)Indemnification to the liquidators and certain others for existing liabilities or expenses or liabilities arising during the liquidation process. The indemnifications are limited to distributions made from the subsidiary to its parent either prior or subsequent to liquidation or are not explicitly stated in the agreements. The indemnifications generally expire two to seven years subsequent to the date of dissolution of the entities. The exposure noted only includes those cases where the agreements provide for specific limits.

In connection with their sales of various businesses, WPD and its affiliates have provided the purchasers with indemnifications that are standard for such transactions, including indemnifications for certain pre-existing liabilities and environmental and tax matters or have agreed to continue their obligations under existing third-party guarantees, either for a set period of time following the transactions or upon the condition that the purchasers make reasonable efforts to terminate the guarantees. Additionally, WPD and its affiliates remain secondarily responsible for lease payments under certain leases that they have assigned to third parties.

(b)Relates to certain obligations of discontinued or modified electric associations that were guaranteed at the time of privatization by the participating members. Costs are allocated to the members and can be reallocated if an existing member becomes insolvent. At September 30, 2020, WPD has recorded an estimated discounted liability for which the expected payment/performance is probable. Neither the expiration date nor the maximum amount of potential payments for certain obligations is explicitly stated in the related agreements, and as a result, the exposure has been estimated.

(c)LKE provides certain indemnifications covering the due and punctual payment, performance and discharge by each party of its respective obligations. The most comprehensive of these guarantees is the LKE guarantee covering operational, regulatory and environmental commitments and indemnifications made by WKE under a 2009 Transaction Termination Agreement. This guarantee has a term of 12 years ending July 2021, and a maximum exposure of $200 million exclusive of certain items such as government fines and penalties that may exceed the maximum. Additionally, LKE has indemnified various third parties related to historical obligations for other divested subsidiaries and affiliates. The indemnifications vary by entity and the maximum exposures range from being capped at the sale price to no specified maximum. LKE could be required to perform on these indemnifications in the event of covered losses or liabilities being claimed by an indemnified party. LKE cannot predict the ultimate outcomes of the various indemnification scenarios, but does not expect such outcomes to result in significant losses above the amounts recorded.

(d)Pursuant to the OVEC power purchase contract, LG&E and KU are obligated to pay for their share of OVEC's excess debt service, post-retirement and decommissioning costs, as well as any shortfall from amounts included within a demand charge designed and expected to cover these costs over the term of the contract. LKE's proportionate share of OVEC's outstanding debt was $105 million at September 30, 2020, consisting of LG&E's share of $73 million and KU's share of $32 million. The maximum exposure and the expiration date of these potential obligations are not presently determinable. See "Energy Purchase Commitments" in Note 13 in PPL's, LKE's, LG&E's and KU's 2019 Form 10-K for additional information on the OVEC power purchase contract.

In March 2018, a sponsor with a 4.85% pro-rata share of OVEC obligations filed for bankruptcy under Chapter 11 and, in August 2018, received a rejection order for the OVEC power purchase contract in the bankruptcy proceeding. OVEC and other entities challenged the contract rejection, the

bankruptcy plan confirmation and regulatory aspects of the plan in various forums. In May 2020, OVEC and the relevant sponsor announced a settlement resolving all disputed matters in the bankruptcy and other proceedings, including providing that the sponsor will withdraw its request to reject the power purchase agreement. The settlement was implemented in July 2020. Periodically, OVEC and certain of its sponsors, including LG&E and KU, may consider certain potential additional credit support actions to preserve OVEC's access to credit markets, including establishing or continuing debt reserve accounts or other changes involving OVEC's existing short and long-term debt.
